In this report, it is demonstrated that chiral vinyl aziridines can be stereospecifically ring expanded. This synthetic approach allows controlled access to chiral 2,5-cis- or 2,5-trans-3-pyrroline products from starting materials with the appropriate aziridine geometry. Twenty three ring expansion examples, most of which feature a stereospecific cyclization, are presented.
在这份报告中,证明了手性乙烯基氮丙啶可以立体有择地扩环。这种合成方法允许从具有适当氮丙啶几何结构的起始材料中受控地获得手性 2,5-顺式- 或 2,5-反式-3- 吡咯啉产物。介绍了二十三个环扩展示例,其中大多数具有立体特异性环化。
