to reaction discovery. Herein we report an enantioselective aza‐Stetter reaction that proceeds via imine umpolung using N‐heterocyclic carbene catalysis. The reaction proceeds with high levels of enantioselectivity (all ≥96:4 er) and good generality (21 examples). Mechanistic studies are reported and are consistent with turnover‐limiting addition of the NHC to the imine.
亚胺的催化催化作用仍然是反应发现的未开发方法。在本文中,我们报告了使用N杂环卡宾催化通过
亚胺umpolung进行的对映选择性aza-Stetter反应。反应以高
水平的对映选择性(均≥96:4 er)和良好的通用性(21个实例)进行。已报道了机理研究,并且与限制向
亚胺中添加NHC的营业额一致。
