A simple and practical route for the asymmetric synthesis of (S)-4-(4-fluorophenyl)-1,4,5,6-tetrahydro-6oxo-3-pyridinecarboxylic acid (1) is presented. The procedure comprises catalytic desymmetrization of a meso-anhydride using a chiral thiourea organocatalyst, followed by selective formylation and
An efficient method for the preparation of 2-substituted 4-aryl-4,5-dihydro-3,1-benzoxazepine derivatives under mild conditions has been developed. The reaction of 2-(2-aminophenyl)ethanols 1 with acid chlorides in the presence of excess Et 3 N in THF at room temperature gave the corresponding Nacyl
