A convenient copper-catalyzedcascade cyclization/cyanation reaction for the construction of cyano-containing γ-lactams was developed. The protocol employed TMSCN as the cyano source and proceeded in water under simple conditions. Mechanistic studies indicated this reaction involved an amidyl radical initiated cascade 5-exo-trig cyclization/cyanation process. It is capable of generating a series of
