The Aryne-Abramov Reaction as a 1,2-Benzdiyne Platform for the Generation and Solvent-Dependent Trapping of 3-Phosphonyl Benzynes was written by Bembenek, Brianna M.;Petersen, Maya M.

Synthetic methodol. utilizing two aryne intermediates (i.e., a formal benzdiyne) enables the rapid generation of structurally complex mols. with diverse functionality. This report describes the sequential generation of two ortho-benzyne intermediates for the synthesis of 2,3-disubstituted aryl phosphonates. Aryl phosphonates have proven useful in medicinal chem. and materials science, and the reported methodol. provides a two-step route to functionally dense variants by way of 3-phosphonyl benzyne intermediates. The process begins with regioselective trapping of a 3-trifloxybenzyne intermediate by an O-silyl phosphite in an Abramov-like reaction to bond the strained Csp carbons with phosphorus and silicon. Standard aryne-generating conditions follow to convert the resulting 2-silylphenyl triflate into a 3-phosphonyl benzyne, which readily reacts with numerous aryne trapping reactants to form a variety of 2,3-difunctionalized aryl phosphonate products. DFT computational studies shed light on important mechanistic details and revealed that 3-phosphonyl benzynes are highly polarizable. Specifically, the distortion in the internal bond angles at each of the Csp atoms was strongly influenced by both the electronegativity of the phosphonate ester groups as well as the dielec. of the computational solvation model. These effects were verified exptl. as the regioselectivity of benzyl azide trapping increased with more electroneg. esters and/or increasingly polar solvents. Conversely, replacing the conventional solvent, acetonitrile, with nonpolar alternatives provided attenuated or even inverted selectivities. Overall, these studies showcase new reactivity of benzyne intermediates and extend the aryne relay methodol. to include organophosphonates. Furthermore, this work demonstrates that the regioselectivity of aryne trapping reactions could be tuned by simply changing the solvent. In the experiment, the researchers used many compounds, for example, Methyl 3,5-dihydroxy-4-iodobenzoate (cas: 338454-02-7Synthetic Route of C8H7IO4).

Methyl 3,5-dihydroxy-4-iodobenzoate (cas: 338454-02-7) belongs to iodide derivatives.

Antitumor benzothiazoles. 26. 2-(3,4-Dimethoxyphenyl)-5-fluorobenzothiazole (GW 610, NSC 721648), a simple fluorinated 2-arylbenzothiazole, shows potent and selective inhibitory activity against lung, colon, and breast cancer cell lines was written by Mortimer, Catriona G.;Wells, Geoffrey;Crochard, Jean-Philippe;Stone, Erica L.;Bradshaw, Tracey D.;Stevens, Malcolm F. G.;Westwell, Andrew D.. And the article was included in Journal of Medicinal Chemistry in 2006.Category: iodides-buliding-blocks This article mentions the following:

A series of new 2-phenylbenzothiazoles has been synthesized on the basis of the discovery of the potent and selective in vitro antitumor properties of 2-(3,4-dimethoxyphenyl)-5-fluorobenzothiazole (I; GW 610, NSC 721648). Synthesis of analogs substituted in the benzothiazole ring was achieved via the reaction of o-aminothiophenol disulfides with substituted benzaldehydes under reducing conditions. Compounds were evaluated in vitro in four human cancer cell lines, and I was found to possess exquisitely potent antiproliferative activity (GI₅₀ < 0.1 nM for MCF-7 and MDA 468). Potent and selective activity was also observed in the NCI 60 human cancer cell line panel. Structure-activity relationships study established that I stands on a pinnacle of potent activity, with most structural variations having a deactivating in vitro effect. Mechanistically, this new series of agents contrasts with the previously reported 2-(4-aminophenyl)benzothiazoles; I is not reliant on induction of CYP1A1 expression for antitumor activity. In the experiment, the researchers used many compounds, for example, 3-Iodo-4-methoxybenzaldehyde (cas: 2314-37-6Category: iodides-buliding-blocks).

3-Iodo-4-methoxybenzaldehyde (cas: 2314-37-6) belongs to iodide derivatives. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine. Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond.Category: iodides-buliding-blocks

Palladium-Catalyzed Carbonylative Couplings of Vinylogous Enolates: Application to Statin Structures was written by Makarov, Ilya S.;Kuwahara, Takashi;Jusseau, Xavier;Ryu, Ilhyong;Lindhardt, Anders T.;Skrydstrup, Troels. And the article was included in Journal of the American Chemical Society in 2015.SDS of cas: 34091-51-5 This article mentions the following:

The first Pd-catalyzed carbonylative couplings of aryl and vinyl halides with vinylogous enolates are reported to generate products derived from C-C bond formation exclusively at the γ-position. Good results were obtained with a dienolate derivative of acetoacetate (1,3-dioxin-4-one). E.g., in presence of Pd(dba)₂, Xantphos, and LiHMDS in THF in a two-chamber reactor system using SilaCOgen as the carbon monoxide source, carbonylative coupling of 4-NCC₆H₄I with 2,2,6-trimethyl-4H-1,3-dioxin-4-one gave 77% I. These transformations occurred at room temperature and, importantly, with only stoichiometric carbon monoxide in a two-chamber reactor. The methodol. was applied to the synthesis of two members of the statin family generating the cis-3,5-diol acid motif by a γ-selective carbonylation followed by a cis-stereoselective reduction of the 3,5-dicarbonyl acid intermediates.
