[reaction: see text] A series of experiments are described that suggest that the Rh-catalyzed reductive aldol reaction proceeds by addition of a Rh(I) hydride, generated in situ, to the reacting acrylate followed by a stereochemistry-controlling aldol addition reaction. On the basis of this hypothesis, reaction conditions are engineered that allow for increased substrate scope.
[反应:参见正文]描述了一系列实验,这些实验表明,通过向反应的丙烯酸酯中添加原位生成的氢化Rh(I)氢化物,然后进行立体化学控制的醛醇加成反应,可以进行Rh催化的还原性醇醛缩合反应。 。基于该假设,设计了可以增加底物范围的反应条件。
