Synthesis of substituted carbazoles via electrocyclization of in situ generated enamines from 1-phenylsulfonyl-2/(3)-methyl-3/(2)-vinylindoles and DMF·DMA/DMA·DMA
摘要:
Interaction of 2/(3)-methyl-3/(2)-vinylindoles and DMF center dot DMA/DMA center dot DMA at 110 degrees C led to the in situ generation of enamines, which on concurrent electrocyclization followed by subsequent aromatization afforded substituted carbazoles.
