An efficient method for highly alpha-regioselective nucleophilic substitution of the Baylis-Hillman acetates with indoles catalyzed by AgOTf in high yields (72-99%) has been developed. Reductive cyclization of the substitution products furnished the azepinoindole derivatives in good yields (up to 93%).
