摘要

Amide of an octanoic acid possessing an aryl group at C3 position is a highly potent ACAT inhibitor. In this paper, we describe a synthetic access to this class of compounds as optically active forms. The key reaction is substitution of the allylic picolinate of (S, Z)-8- (benzyloxy) oct-5-en-4-ol with a copper reagent derived from (benzo [d][1, 3] dioxol-4-yl) MgBr and CuBr· Me2S to produce anti SN2′ product regio-and stereo-selectively. The ...
