Regioselective dibromination of methyl indole-3-carboxylate and application in the synthesis of 5,6-dibromoindoles


Organic & Biomolecular Chemistry 9(14): 5021-5023
Regioselective dibromination of methyl indole-3-carboxylate and application in the synthesis of 5,6-dibromoindoles
Treatment of methyl indole-3-carboxylate with bromine in acetic acid gives methyl 5,6-dibromoindole-3-carboxylate regioselectively, from which the parent 5,6-dibromoindole can be accessed via a one-pot, microwave-mediated ester hydrolysis and decarboxylation. Application of these building blocks in syntheses of natural and non-natural 5,6-dibromoindole derivatives, including meridianin F and 5,6-dibromo-2'-demethylaplysinopsin, is reported.
