Convenient Syntheses of Cyclic Carboxamides from α,β,γ,δ and ε-halocarboxamides under Phase Transfer Conditions

Piperazine-2,5-diones (2) were prepared by N-alkylation between two molecules of α-halocarboxamides (1) in the presence of a phase transfer catalyst in yields of 64-88percent. β,γ,δ and ε-Lactams (6,9 and 13) were similarly synthesized by intramolecular N-alkylation of the corresponding halocarboxamides (5, 8 and 12) under phase transfer conditions in 53-99percent yields.Keywords--piperazine-2,5-dione; β-lactam; γ, δ, and ε lactams; bis-β-lactam; phase transfer catalyst; intramolecular N-alkylation
