2-Furylcarbinols undergo a smooth aza-Piancatelli rearrangement followed by Friedel–Crafts alkylation with (1H-pyrrol-1-yl)aniline, in the presence of In(OTf)3 at room temperature to afford the corresponding hexahydrobenzo[b]cyclopenta[f]pyrrolo[1,2-d][1,4]diazepin-11(4aH)-one scaffolds.
2-呋喃基甲醇经过平滑的氮杂皮安卡特利重排反应,随后在室温下与(1H-吡咯-1-基)苯胺在In(OTf)3存在下经过Friedel-Crafts烷基化反应,得到相应的六氢苯并[b]环戊[f]吡咯[1,2-d][1,4]二氮杂环十一(4aH)-酮骨架。
