A highly effective synthesis of 2,3-fused pyrroles from cyclic ketones has been achieved. The transformation includes a rhodium-catalyzed reaction of 4-alkenyl-1-sulfonyl-1,2,3-triazoles featuring an unusual 4π electrocyclization. The methodology was further extended to the synthesis of indoles using a one-pot reaction starting from 1-ethynylcyclohexenes.
已经实现了由环酮高效合成 2,3-稠合吡咯。该转化包括 4-链烯基-1-磺酰基-1,2,3-三唑的铑催化反应,具有不寻常的 4π 电环化。该方法进一步扩展到使用从 1-乙炔基环己烯开始的一锅反应合成吲哚。
