Bakers' yeast reduction of 3-acyltetrahydrothiopyran-4-ones is regio- and enantioselective, yielding predominantly (3R,4S)-3-acyl-4- hydroxytetrahydrothiopyranes with high optical purity. This reduction method coupled with the Raney-nickel desulfurization provides a ready access to the rice and maize weevils aggregation pheromone, (−)-(4R,5S)-sitophilure, in high optical purity.
贝克的3-酰基四氢噻喃-4-酮的酵母还原具有区域和对映选择性,主要产生具有高光学纯度的(3 R,4 S)-3-酰基-4-羟基四氢噻喃。这种还原方法与阮内镍脱硫技术相结合,可提供高光学纯度的水稻和玉米象鼻虫聚集信息素(-)-(4 R,5 S)-sitophilure。
