Abstract

Volume 28, No. 2, 1996 OPPI BRIEFS reagent"! The derivatives of DAPDO (1) have great potential in biochemistry* and synthesis9 and may be obtained by the condensation of aldehydes with piperazinedione (PD0)'O or with DAPDO using strong bases (eg t-BuOK)," by the use of phosphorus ylide, I2 by microwave irradiation'> or using phase-transfer~ atalysis'~ in a few hours to a few days in moderate to excellent yields; however, there ...
