A facile synthetic route has been developed for the preparation of pyrrolizinone derivatives employing N-allyl imides as starting materials. The nucleophilic addition of a vinyl Grignard reagent/RCM/elimination sequence afforded pyrrolizinones in good yields and has been applied for the preparation of naturally occurring quinolactacide and marinamide.
已经开发了一种以N-烯丙基酰亚胺为起始原料制备吡咯烷酮衍生物的简便合成途径。乙烯基格氏试剂/ RCM /消除序列的亲核加成以良好的收率提供了吡咯烷酮,并已用于制备天然存在的喹诺酸交酯和马来酰胺。
