Hydrogenation of enantioenriched β-hydroxy ketones promoted by the catalyst generated in situ from commercially available and inexpensive RuCl3 and PPh3 under hydrogen pressure allowed the efficient preparation of a variety of anti-1,3-diols in good yields and with a high level of diastereoselectivity. This method should be an interesting alternative to organoboron reagents for the diastereoselective
在氢气压力下,由市售且廉价的 RuCl3 和 PPh3 原位生成的催化剂促进对映体富集的 β-羟基酮的氢化允许以良好的收率和高水平的非对映选择性有效制备各种抗 1,3-二醇. 这种方法应该是一种有趣的替代有机硼试剂用于 β-羟基酮的非对映选择性还原。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
