Article abstract of DOI:10.1016/S0040-4020(01)90232-7

Mixed diesters, ω-amide and ω-thioesters are obtained from both N-Boc ethyl pyroglutamate and pyroaminoadipate under neutral or basic conditions.Under neutral conditions, the reaction is catalyzed by KCN and the use of ultrasound speeds up the process.In
