The oxidative hydrolysis of different trifluoroacetyl-protected N-(2-chloroallyl)anilines, promoted by calcium hypochlorite, is able to yield several not previously described α-arylamino-α'-chloropropan-2-ones, very valuable building blocks that are usefu

N-(trifluoroacetyl)indoles (3) are produced in high yield from appropriately ring-substituted N-(trifluoroacetyl)-2-anilino acetals (2) in boiling trifluoroacetic acid containing excess trifluoroacetic anhydride.Mild saponification provides the free indoles nearly quantitatively.The scope of the reaction is discussed.The ring closure follows solvolytic substitution of a trifluoroacetoxy group for one of the ethoxy groups in 2.The method has been extended to cyclization of N-(trifluoroacetyl)-α-anilinoacetone in hot polyphosphoric acid followed by saponification to yield 3-methylindole.
