摘要

本文首次介绍了铱催化的乙烯基叠氮化物和乙烯基苯并恶嗪酮的对映选择性偶联反应。乙烯基叠氮化物经过串联烯丙基烷基化/间歇施密特重排过程，生成了对映体富集的 3,4-二氢喹啉-2(1H)-亚胺，这是一类新的 N-杂环化合物。在 CH3CO2H 的存在下，发生了传统的不对称烯丙基取代反应，从而获得了非外消旋烯丙基酰胺。通过对产物进行合成转化，构建了手性胺、酰胺和 N-杂环。

Iridium-Catalyzed Highly Enantioselective and Chemodivergent Coupling Reaction of Vinyl Azides and Vinyl Benzoxazinones

The first Iridium-catalyzed enantioselective coupling reaction of vinyl azides and vinyl benzoxazinones is presented. Vinyl azides underwent a tandem allylic alkylation/interrupted Schmidt rearrangement process to produce enantioenriched 3,4-dihydroquinolin-2(1H)-imines, a new class of N-heterocyles. In the presence of CH3CO2H, a conventional asymmetric allylic substitution occurred to provide access to nonracemic allylic amides. The synthetic transformations of product were implemented to construct chiral amine, amide and N-hetero polycycle.
