In this work, an operationally simple, one-pot, straightforward synthesis of N-aryl γ- and δ-lactams has been disclosed. Readily available, cheap γ-/δ-amino acids and aryl halides were used as starting materials to synthesize a variety of N-aryl γ- and δ-lactams by using copper-mediated cascade intramolecular amidation/C−N-coupling sequence.
A quick, efficient, one-pot, BF3·OEt2-mediated synthesis of substituted N-aryl lactams in good to excellent yields by reaction of various substituted arenes with a variety of ω-azido alkanoic acid chlorides at room temperature is reported.
