A highly enantioselective synthesis of trisubstituted allenoates through the isomerization of alkynoates catalyzed by benzothiadiazine organocatalyst is demonstrated. From the examination of the reaction time course, that organocatalyst predominantly recognized one of the enantiomers of alkynoates and mediated the isomerization of alkynoates through dynamic kinetic resolution is disclosed.

A simple, efficient and user-friendly protocol for the preparation of structurally diverse enaminones e.g., I from enamides e.g., II has been developed. The strategy is based on a photo-induced intramol. Fries-type rearrangement. The photochem. transformation proceeds under mild reaction conditions, applies to a broad substrate range, is highly economic, and limits the amount of waste produced. The proposed methodol. was used as a key step in the synthesis of dihydrojasmone an important fragrance compound

Yang, Ze-Peng published the artcileThe Asymmetric Synthesis of Amines via Nickel-Catalyzed Enantioconvergent Substitution Reactions, Product Details of C6H13I, the publication is Journal of the American Chemical Society (2021), 143(7), 2930-2937, database is CAplus and MEDLINE.

Herein, two mild methods was reported for the catalytic enantioconvergent synthesis of protected dialkyl carbinamines such as RCHXR¹ [R = i-Bu, n-hexyl, (CH₂)₅F, etc.; R¹ = Et, i-Bu, (CH₂)₂Ph, etc.; X = NHBoc, Phth, NHFmoc, etc.], both of which use a chiral nickel catalyst to couple an alkylzinc reagent with α-phthalimido alkyl chloride or an N-hydroxyphthalimide (NHP) ester of a protected α-amino acid. The methods were versatile, providing dialkyl carbinamine derivatives that bear an array of functional groups. Further, for couplings of NHP esters a one-pot variant wherein the NHP ester was generated in situ, allowing the generation of enantioenriched protected dialkyl carbinamines in one step from com. available amino acid derivatives was also described. The utility of this method by applying it to the efficient catalytic enantioselective synthesis of a range of interesting target mols. was demonstrated.

Blakemore, Caroline A. published the artcileScalable, telescoped hydrogenolysis-enzymic decarboxylation process for the asym. synthesis of (R)-α-heteroaryl propionic acids, SDS of cas: 884495-13-0, the publication is Organic Process Research & Development (2021), 25(3), 421-426, database is CAplus.

Enantiopure α-aryl propionic acids are useful building blocks for pharmaceutical research and can be accessed enzymically using arylmalonate decarboxylases (AMDases) from the corresponding malonic acids. However, the intrinsic instability of malonic acids is a major drawback to this approach in which spontaneous decarboxylation can occur, subsequently eroding enantioselectivity and giving rise to racemic products. This was particularly evident for a panel of N-heterocyclic propionic acids that we wished to access using the approach. Herein, we describe a process to overcome the spontaneous decarboxylation problem in which hydrogenolysis of the corresponding dibenzyl malonates was performed in a biphasic toluene-basic aqueous buffer mixture and telescoped into the subsequent AMDase step. This procedure enabled compounds to be accessed in high enantioselectivities and was successfully demonstrated on 120 g with high yield (76%) and ee (98%).

Fritzemeier, Russell published the artcileDiscovery of In Vivo Active Sphingosine-1-phosphate Transporter (Spns2) Inhibitors, Recommanded Product: 4-Iodobenzohydrazide, the publication is Journal of Medicinal Chemistry (2022), 65(11), 7656-7681, database is CAplus and MEDLINE.

Sphingosine 1-phosphate (S1P) is a pleiotropic signaling mol. that interacts with five G-protein-coupled receptors (S1P1-5) to regulate cellular signaling pathways. S1P export is facilitated by Mfsd2b and spinster homolog 2 (Spns2). While mouse genetic studies suggest that Spns2 functions to maintain lymph S1P, Spns2 inhibitors are necessary to understand its biol. and to learn whether Spns2 is a viable drug target. Herein, we report a structure-activity relationship study that identified the first Spns2 inhibitor 16d (SLF1081851)(I). In vitro studies in HeLa cells demonstrated that 16d inhibited S1P release with an IC₅₀ of 1.93 μM. Administration of 16d to mice and rats drove significant decreases in circulating lymphocyte counts and plasma S1P concentrations, recapitulating the phenotype observed in mice made deficient in Spns2. Thus, 16d has the potential for development and use as a probe to investigate Spns2 biol. and to determine the potential of Spns2 as a drug target.

Herein, we report a general and simplified synthesis of fluorophosphonates directly from p-nitrophenylphosphonates. This FP on-demand reaction is mediated by a com. available polymer-supported fluoride reagent that produces a variety (25 examples) of fluorophosphonates in high yields while only requiring reagent filtration for pure fluorophosphonate isolation. This reaction protocol facilitates the rapid profiling of serine hydrolases with diverse and novel sets of activated phosphonates with differential proteome reactivity. Moreover, slight modification of the procedure into a reaction-to-assay format has enabled addnl. screening efficiency.

(-)-Shikimic acid, was converted into both enantiomers of 2-hydroxyoxabicyclo[4.1.0]hept-3-ene-4-carboxylic acid which were attached to a solid support via a photocleavable linker. Tandem acylation-1,3-dipolar cycloaddition with nitrones yielded tetracyclic templates I. After development of several efficient coupling reactions of I and completion of extensive validation protocols, a split-pool synthesis yielded a binary encoded library calculated to contain 2.18 million polycyclic compounds These compounds are compatible with miniaturized cell-based forward chem. genetic assays designed to explore biol. pathways and reverse chem. genetic assays designed to explore protein function. As a simple illustration of the potential of these compounds, several were shown to activate a TGF-β-responsive reporter gene in mammalian cells.

A combinatorial library of 2.18 million octahydrobenzoisoxazoles I (R = 2-I, 3-I, 4-I, 2-R⁴CC, 3-R⁴CC, 4-R⁴CC; R¹ = alkyl, cycloalkyl, arylalkyl; R² = alkyl, cycloalkyl, aryl, arylalkyl, heteroaryl; R³ = NH₂, CH₂CONH₂, (CH₂)₅CONH₂; R⁴ = alkyl, aryl, arylalkyl) has been generated to give a set rigid, stereochem. defined, and structurally diverse mols. The libraries are prepared in six steps from either enantiomer of oxacycloheptane II by linking to a solid support with one of three linkers, esterification and dipolar cycloaddition with arylmethyl glycine nitrones, Sonogashira coupling of the product iodoaryl derivatives with alkynes, lactone cleavage with amines, acylation of the free alcs. with acids and acyl coupling reagents, and photochem. cleavage from the resin. Sublibraries of I were prepared to test the reactivity of alkynes, amines, and acids in the preparative sequence towards I and the purity of the products generated. Libraries generated by this sequence are spatially separated and encoded, allowing for controlled release of libraries into solution and for cell-based testing of the libraries.

Schwickert, Marvin published the artcileDiscovery of Inhibitors of DNA Methyltransferase 2, an Epitranscriptomic Modulator and Potential Target for Cancer Treatment, Application of (S)-tert-Butyl 2-((tert-butoxycarbonyl)amino)-4-iodobutanoate, the publication is Journal of Medicinal Chemistry (2022), 65(14), 9750-9788, database is CAplus and MEDLINE.

Selective manipulation of the epitranscriptome could be beneficial for the treatment of cancer and also broaden the understanding of epigenetic inheritance. Inhibitors of the tRNA methyltransferase DNMT2, the enzyme catalyzing the S-adenosylmethionine-dependent methylation of cytidine 38 to 5-methylcytidine, were designed, synthesized, and analyzed for their enzyme-binding and -inhibiting properties. For rapid screening of potential DNMT2 binders, a microscale thermophoresis assay was established. Besides the natural inhibitors S-adenosyl-L-homocysteine (SAH) and sinefungin (SFG), we identified new synthetic inhibitors based on the structure of N-adenosyl-2,4-diaminobutyric acid (Dab). Structure-activity relationship studies revealed the amino acid side chain and a Y-shaped substitution pattern at the 4-position of Dab as crucial for DNMT2 inhibition. The most potent inhibitors are alkyne-substituted derivatives, exhibiting similar binding and inhibitory potencies as the natural compounds SAH and SFG. CaCo-2 assays revealed that poor membrane permeabilities of the acids and rapid hydrolysis of an ethylester prodrug might be the reasons for the insufficient activity in cellulo.
