Efficient Synthesis of 2,5-Diketopiperazines by Staudinger-Mediated Cyclization
摘要:
Solution- and solid-phase Staudinger-mediated cyclizations were assessed to efficiently prepare hetero-2,5-diketopiperazines from their protected azido dipeptide thioesters under microwave irradiation. Short reaction time, good yields and ease of purification are the main assets of this methodology.
