tert-Butyl 3-diazo-2-oxopyrrolidine-1-carboxylate synthesized on multigram scale has been employed to introduce a privileged NH-2-pyrrolidone moiety via oxygen, sulfur and nitrogen atom to partner molecules via RhII-catalyzed X–H insertion followed by Boc group removal. Further manipulation of pyrrolidine moiety has been exemplified.

Via intramolecular C-H insertion of N-cumyl α-diazo acetamides, γ-lactams were efficiently synthesized with excellent regioselectivity. A concise route for the preparation of pregabalin (79% overall yield) and 3-benzyloxy pyrrolidine (21% overall yield) were reported.
