The one-pot 2 alpha- and 3 alpha-functionalization of 2,3-disubstituted indoles using a hypervalent iodine reagent has been developed. The substitution at the 2 alpha-position of indoles took place using phenyliodinebis(trifluoroacetate) with oxygen and carbon nucleophiles in moderate yields. The combination of iodosobenzene and trimethylsilyl azide afforded 3 alpha-azide derivatives preferentially. The latter reaction was applied to other 2,3-disubstituted indoles.
