Easy to cope with: Experimental evidence was found to support an enzymatic [3,3]‐sigmatropic rearrangement catalyzed by dimethylallyltryptophan (DMAT) synthase (see scheme). A bio‐inspired system showed the feasibility of Cope rearrangement to the C‐4 position of the indole nucleus. The tricyclic benzo[cd]indole core of welwitindolinones and dragmacidin E was synthesized using this transformation.
易于应对:发现实验证据支持由二甲基烯丙基色氨酸(DMAT)合酶催化的酶促[3,3]-σ重排(请参阅方案)。一个受生物启发的系统显示了Cope重排到吲哚核的C-4位置的可行性。使用这种转化合成了welwitindolinones和drammacidin E的三环苯并[ cd ]吲哚核。
