This work reports the possibility of controlling the sense of enantio‐ and diastereoinductions in the sequential hydroformylation and aldol reactions via the judicious combination of a chiral metal catalyst with a chiral organocatalyst. The diastereoselectivity of the reaction between styrene, syngas and acetone can be increased by using a matched pair of catalysts, [rhodium/(2S,4S)‐Chiraphite]/(S)‐organocatalyst
这项工作报告了通过明智地将手性
金属催化剂与手性有机催化剂结合使用,可以控制顺序加氢甲酰化和醛醇缩合反应中对映体和非对映体引入的感觉的可能性。
苯乙烯,合成气和
丙酮之间的反应的非对映选择性可以增加通过使用匹配的一对催化剂,[
铑/(2小号,4小号)-Chiraphite] /(小号)-organocatalyst和下降,但不反转,通过使用一对不匹配的催化剂,[
铑/(2 R,4 R)-Chiraphite] /(S)-有机催化剂。
