摘要:
The synthesis of (2S,2'S)-2,3-bis(aziridin-2-yl)quinoxaline 4 from D-mannitol is reported. Reductive aminocyclization of diazidodiols has been achieved by polymer-supported PPh3 in a suitable manner. The N-Boc and N-Tos aziridines 4b and 4c have been reacted with different nucleophiles either in protic or aprotic media. (C) 2002 Elsevier Science Ltd. All rights reserved.
