摘要：
Aliphatic α-oxo ketene cyclic dithioacetals 1 were reacted with allyl magne-sium bromide to afford the 1,2-addition products 2.Catalyzed by boron trifluorideetherate,the adducts 2 were etherified by methanol to afford the corresponding methylethers 3.This process provides a new method for the protection of the acid sensitivehydroxyl group in 2 under mild condition.
