A short divergent approach to highly substituted carbazoles and β-carbolines via in situ-generated diketoindoles

, (2020/03/03)
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 β-carbolines, starting from readily

Starting from common intermediate methyl 1-hydroxy-9 H -carbazole-3-carboxylate, synthetic routes toward murrayaquinone A, olivacine, and N -methylcalothrixin B were developed.

A new route to substituted β-carbolines and carbazoles is described. Diketoindole intermediates, prepared by Friedel-Crafts acylations of 3-substituted indoles, have been converted to 3-hydroxycarbazoles and β-carbolines in good yields, 51-96% and 82-97%, respectively. This method also allows for the formation of 4-substituted β-carbolines. The application of this methodology to the synthesis of the natural products hyellazole and 6-chlorohyellazole is also described.
