A convenient synthesis of 1,2-dihydro-3H-indol-3-ones and 1,2-dihydro-2H-indol-2-ones by Baeyer-Villiger oxidation

Bourlot,Desarbre,Merour

, p. 411 - 416 (1994)

The Baeyer-Villiger rearrangement of substituted 1H-indole-3-carbaldehydes afforded the corresponding substituted 1,2-dihydro-3H-indol-3-ones. The influence of 3-carbonyl and 1-protecting groups has been examined. Reaction has been extended to 1H-indole-2-carbaldehydes and used for synthesis of 1-(phenylsulfonyl)-1H-indol-2-yl trifluoromethanesulfonate.
