A formal [3 + 3] cyclization reaction of 2-indolylmethanols with quinones was realized to furnish indole-fused scaffolds in moderate to excellent yields. This protocol was proceeded smoothly under acid condition, with high high yields and broad substrate scope.

2,3,6-Tribromo-N-phenylsulfonyl-1,4-benzoquinon-4-imines are formed on bromination of 4-arenesulfonamidophenols and N-aryl-sulfonyl-1,4-benzoquinon-4-imines but 2-bromo-N-arylsulfonyl-1,4-naphthoquinon-4-imines are formed from 4-arenesulfonamido-1-naphthols and N-arylsulfonyl-1,4-naphthoquinon-4-imines.
