A facile method for the preparation of chiral secondary alcohols bearing a sulfur-containing functionality using a chemo-enzymatic approach is described, with the aid of baker’s yeast and Candida Antarctica lipase B. A complete set of four stereoisomers of two substituted phenylsulfinylpropan-2-ols were synthesized from β-sulfinyl ketones with excellent enantioselectivity for the first time.
本文介绍了一种利用化学酶法、借助面包酵母和南极念珠菌脂肪酶 B 制备具有含硫官能团的手性仲醇的简便方法,首次以 β-亚磺酰基酮为原料合成了两取代苯基亚磺酰基丙-2-醇的一整套四种立体异构体,并具有极佳的对映选择性。
