(2S,3S)- And (2R,3S)-3-[(tert-butyldimethyl)silyloxy]-1-chlorobutan-2-ol have been obtained with high diastereoselectivity by reduction of enantiopure (S)-3-[(tert-butyldimethyl)silyloxy]-1-chlorobutan-2-one using different reducing agents. The chiral alcohols were transformed into the corresponding (2R,3S)- and (2S,3S)-3-[(tert-butyldimethyl)silyloxy]-1,2-epoxybutane. (C) 1999 Elsevier Science Ltd. All rights reserved.
(2S,3S)- 和 (2R,3S)-3-[(叔丁基二甲基)硅氧基]-1-氯丁烷-2-醇已通过对映纯 (S)-3-[(叔丁基二甲基)硅氧基]-1-氯丁烷-2-酮使用不同的还原剂进行还原,获得高非对映选择性。这些手性醇被转化为相应的 (2R,3S)- 和 (2S,3S)-3-[(叔丁基二甲基)硅氧基]-1,2-环氧丁烷。© 1999 Elsevier Science Ltd. 保留所有权利。
