An extremely mild protocol that employs readily available starting materials, i.e., aldehyde, amine and alkyl diazoacetate, returns structurally diverse N-substituted-C-2/3-difunctionalised aziridines in excellent yields and stereoselectivities when pyridinium triflate is incorporated as an organocatalyst. The reaction process is environmentally benign affording water and nitrogen as the only by-products
当掺入三氟甲磺酸吡啶鎓作为有机催化剂时,使用温和的起始原料即醛,胺和重氮乙酸烷基酯的极其温和的方案以优异的产率和立体选择性返回结构多样的N-取代-C-2 / 3-双官能化氮丙啶。反应过程在环境上是无害的,提供水和氮作为唯一的副产物。该外消旋方案为开发能够产生光学活性氮丙啶的新型不对称有机催化剂铺平了道路。
