Treatment of N-(3-bromo-3-butenyl)pyrrolidine derivatives with tributyltin hydride and AIBN leads to hydrogen atom transfer of the intermediate vinyl radicals to give α-amino radicals which then cyclise stereoselectively yielding pyrrolizidines 1 and 13.
用氢化三丁基锡和AIBN处理N-(3-溴-3-丁烯基)吡咯烷衍生物会导致中间乙烯基自由基的氢原子转移,从而产生α-氨基自由基,然后将其立体选择性地环化生成吡咯烷并1和13。
