acyl-based carbanion equivalents. We herein report an alternative strategy that is based on the use of aldehydes as alkyl carbanion equivalents in a reductive coupling with aryl imines. A wide array of secondary amines can be synthesized in moderate to high yields. This reaction is mediated by hydrazine and catalyzed by ruthenium(II) complexes, and it tolerates various functional groups, such as esters, amides
合成胺的经典方法之一涉及通过烯醇酸酯化学或基于酰基的碳负离子等同物偶联羰基化合物和亚胺。我们在本文中报告了一种替代策略,该策略基于在与芳基亚胺的还原偶联中使用醛作为烷基碳负离子当量。可以以中等到高产率合成各种各样的仲胺。该反应由肼介导并由钌(II)配合物催化,并且它可以耐受各种官能团,例如酯,酰胺和腈。
