(R)-3-(p-t-Butylphenylthio)cyclohexan-1-one was reduced with LiAlH(OBut)3 to afford (1S,3R)-3-(p-t-butylphenylthio)cyclohexan-1-o1, while the same reduction with LiBH(s-Bu)3 afforded the (1R,3R) counterpart almost exclusively. Elaboration of each product furnished both enantiomers of optically pure cyclohexenol derivatives.
(R)-3-(pt-Butylphenylthio)cyclohexan-1-one 用 LiAlH(OBut)3 还原得到 (1S,3R)-3-(pt-butylphenylthio)cyclohexan-1-o1,同时用 LiAlH(OBut)3 还原得到 (1S,3R)-3-(pt-Butylphenylthio)cyclohexan-1-o1 LiBH(s-Bu)3 几乎完全提供了 (1R,3R) 对应物。每种产品的加工都提供了光学纯环己烯醇衍生物的两种对映异构体。
