摘要:

以螺环膦氧化合物为催化剂及三氯硅氢为还原剂, 发展了手性Lewis碱催化的烯酮与醛的不对称还原-Aldol反应. 该类催化剂在查耳酮以及类似物与各种醛的不对称还原-Aldol反应中表现出较高的反应活性和良好的立体选择性, 以较好的产率(45%-88%)、中等到优秀的非对映选择性(8:92-100:0)以及最高达95%的ee值得到相应的还原Aldol产物.

Abstract:

A spiro bisphosphine oxide (SpinPO) was found to be an efficient chiral Lewis base catalyst in asymmetric reductive aldol reaction of enones and aldehydes in the presence of trichlorosilane as the reductant, affording a variety of β-hydroxyketones in good yields with moderate to high levels of diastereo- and enantioselectivities.

Key words: Aldehyde, Asymmetric catalysis, Enone, Lewis base, Reductive aldol reaction, Spiro bisphosphine oxide
