Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 75732-01-3, is researched, SMILESS is [Cu]C1=C(C)C=C(C)C=C1C, Molecular C9H11CuJournal, Tetrahedron called A simplified catalytic system for direct catalytic asymmetric aldol reaction of thioamides; application to an enantioselective synthesis of atorvastatin, Author is Kawato, Yuji; Iwata, Mitsutaka; Yazaki, Ryo; Kumagai, Naoya; Shibasaki, Masakatsu, the main research direction is atorvastatin enantioselective synthesis; ketoester preparation amination cyclization; hydroxyalkyl thioamide preparation lithium reagent; thioamide aldehyde aldol reaction Cu catalyst.Reference of Mesitylcopper(I).
A new catalytic system was developed for the direct catalytic asym. aldol reaction of thioamides. The new lithium-free Cu catalyst (second-generation catalyst) exhibited enhanced catalytic efficiency over the previously developed catalyst comprising [Cu(CH3CN)4]PF6/Ph-BPE/LiOAr (first-generation catalyst), which required a tedious catalyst preparation process. In the reaction with the second-generation catalyst, the intermediate Cu-aldolate functioned as a Bronsted base to generate thioamide enolate, efficiently driving the catalytic cycle. The present aldol methodol. culminated in a concise asym. synthesis of atorvastatin I (Lipitor: atorvastatin calcium), a widely prescribed HMG-CoA reductase inhibitor for lowering low-d. lipoprotein cholesterol.
