Abstract
Based on an aza-alkylation/Michael addition cascade reaction developed by Kim and co-workers we have developed divergent cascade reactions leading to either highly substituted 1-hydroxycarbazoles, 3-hydroxycarbazoles or beta-carbolines, starting from readily accessible ortho-arylsulfonylaminobenzaldehydes. Olefination of the aldehyde functionality by aldol condensation or Wittig olefination gave reactive enone intermediates, which underwent the cascade reactions, either in two steps or in one-pot conversions, to give hydroxycarbazoles or complex beta-carbolines.
