As. Bourlot et al., A CONVENIENT SYNTHESIS OF 1,2-DIHYDRO-3H-INDOL-3-ONES AND 1,2-DIHYDRO-2H-INDOL-2-ONES BY BAEYER-VILLIGER OXIDATION, Synthesis, (4), 1994, pp. 411-416
The Baeyer-Villiger rearrangement of substituted 1H-indole-3-carbaldeh
ydes afforded the corresponding substituted 1,2-dihydro-3H-indol-3-one
s. The influence of 3-carbony1 and 1-protecting groups has been examin
ed. Reaction has been extended to 1H-indole-2-carbaldehydes and used f
or synthesis of 1-(phenylsulfonyl)-1H-indol-2-yl trifluoromethanesulfo
nate.
