Efficient synthesis of 2,5-diketopiperazines by Staudinger-mediated cyclization

Beagle, Lucas K.,Hansen, Finn K.,Monbaliu, Jean-Christophe M.,Desrosiers, Michael P.,Phillips, Angela M.,Stevens, Christian V.,Katritzky, Alan R.

, p. 2337 - 2340 (2012)

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. Georg Thieme Verlag Stuttgart · New York.
