The successive reaction of diallyl amines 1 with several alkyllithium reagents and diethyl carbonate leads, after hydrolysis, to the corresponding pyrrolizidine derivatives 3 in a one-pot process; the reaction of intermediates 2 with carbon dioxide affords (Z)-amino acids 8, (E)-amino esters 9 or N-substituted butyrolactams 10.
二烯丙基胺1与几种烷基锂试剂和碳酸二乙酯的连续反应在水解后以一锅法得到相应的吡咯并核苷衍生物3。中间体2与二氧化碳的反应得到(Z)-氨基酸8,(E)-氨基酯9或N-取代的丁内酰胺10。
