employed for the synthesis of dihydropyrroloindoles and dihydropyrrolizines via 5-exo-trig radical cyclization where indoles and pyrroles are used as an acceptor. This radical approach has also been extended for the synthesis of tetrahydrocyclopenta[b]indolones via the Baldwin-disfavored 5-endo-trig cyclization pathway. The formal synthesis of bruceolline J and the totalsynthesis of bruceollines E
铁介导的氢原子转移(HAT)反应可有效地用于通过 5- exo - trig自由基环化合成二氢吡咯并吲哚和二氢吡咯嗪,其中吲哚和吡咯用作受体。这种激进的方法还被扩展到通过鲍德温不喜欢的 5- end - trig环化途径合成四氢环戊[ b ]吲哚酮。采用前一种策略,布鲁斯酚J的正式合成以及布鲁斯酚E和H的全合成都已顺利进行。
