摘要:
Single mode microwave-assisted combinatorial synthesis of biologically interesting quinoxalinones is described. Chiral libraries of quinoxalinone were readily assembled utilizing SNAr reactions, reduction and followed with concomitant cyclization under microwave irradiation. Enantiomeric 1,2,3,4-tetrahydroquinoxalinones were isolated in excellent yield and purity after cleavage. (C) 2003 Elsevier Ltd. All rights reserved.
