Synthesis of piperazinones and benzopiperazinones from 1,2-diamines and organoboronic acids
摘要:
Alkenyl, aryl and heteroaryl boronic acids react with 1,2-diamines and glyoxylic acid to give directly in one step the corresponding piperazinones (2-oxopiperazines). Similarly, the use of monoprotected 1,2-phenylenediamine leads to benzopiperazinones( 1,2,3,4-tetrahydroquinoxalin-2-ones). (C) 2000 Elsevier Science Ltd. All rights reserved.
