Manganese(III) acetate oxidation of alkyl substituted 1- (phenylsulfonyl)indoles
Methyl substituted 1-(phenylsulfonyl)indoles undergo tandem oxidation of the indoline ring and a C-2 methyl group. If there is no alkyl substituent at the C-2 position, nuclear acetoxylation can occur to afford oxindoles.
