摘要：

Asymmetric synthesis of dithiolane aldols 3 was achieved in good yields by using silyl ketene acetal 1, derived from ethyl 1,3-dithiolane-2-carbylate, in the chiral oxazaborolidinone (L-l and D-2)-promoted aldol reaction and desulfurization of 3 resulted in production of acetate aldols 4 in high enantiomerc purity.
