  An efficient sodium hydrogen sulfate catalyzed alkylation of indoles or amines with tertiary enamides has been accomplished in water, affording the pharmacologically and biologically active 2-oxo-1-pyrrolidine derivatives in moderate to excellent yields. The key to our success is the use of NaHSO4 as a low loading, inexpensive, green and recyclable catalyst and the reactions could be scaled up to gram level.

  ABSTRACT Reaction of aromatic amines with tertiary enamides was performed in n-hexane in the presence of acetic acid as an inexpensive and green catalyst at room temperature. This protocol provides the protected aminals through Markovnikov addition reaction with high to excellent yields and regiospecificity. In addition, this procedure was expanded for the synthesis of aminals from commercially available

  Direct alkylation of indoles and amines by tertiary enamides for the synthesis of pharmaceutically active 2-oxo-1-pyrrolidine analogues was described. With only a 0.5 mol% catalyst loading, molecular iodine was demonstrated to be efficiently enough to promote the reaction under neat condition. Only Markovnikov addition product was obtained indicating that the reactions proceeded with excellent regioselectivity.

  A green trend and efficient method for the synthesis of N-substituted γ, δ and ε-lactam derivatives has been developed through one pot multi-component reaction under environmentally benign reaction conditions using FeCl3 as a green catalyst with high atom economy. The present green synthetic protocol shows fascinating properties such as enhanced yield in solvent-free conditions, with high reaction rate, easy workup and absence of column chromatography and also avoids the use of ligands or additives. The versatility of the reaction has been ascertained by using various substituted benzaldehydes, anilines and homologues of lactams.
