Kinetic Resolution of N-Acyl-Thiolactams via Catalytic Enantioselective Deacylation
摘要:
Methanolysis of N-acyl-thiazolidin-2-thiones and -oxazolidin-2-thiones in the presence of acyl transfer catalyst benzotetramisole (BTM) proceeds in a highly enantioselective fashion thus enabling kinetic resolution of these substrates.
2-alkylthio-oxazolines 3a and 3b, respectively, are a novelscaffold for indoleamine2,3-dioxygenase1 (IDO1) inhibitors. Derivatization of the carbonothioates enhanced inhibitory activity against IDO1 and cellular kynurenine production without cytotoxicity and led to the discovery of the related scaffolds carbonodithioates 5 and cyanocarbonimidodithioates 6 as IDO1inhibitors. Incorporation of an OH group provided
