Synthesis of novel 3,4-fused pyrazolidinone gamma-lactam bicyclic moieties from 2,3-dioxo-4-carboxy-5-(substituted)pyrrolidines
A new pathway for the synthesis of novel 3,4-fused pyrazolidinone gamma-lactam (4) starting from 2,3-dioxo-4-carboxy-5-(substituted)pyrrolidines (1) was developed. The key synthetic strategy involved hydrazonation of the precursor 1 followed by subsequent reduction reaction of the enamino ester 2 an...
