Novel access to 1,4-benzodiazepin-2-ones via the Buchwald reaction and application to the synthesis of novel heterocyclics
摘要:
A new two step strategy for the preparation of 1,4-benzodiazepin-2-ones has been developed starting from the 2-halogenobenzophenone under Buchwald conditions (Pd(OAc)(2), XantPhos, Cs2CO3, dioxane 100 degrees C). This strategy has been extended to two 2-halogeno-3-benzoyl-azines (pyridines, pyridazines). (C) 2011 Elsevier Ltd. All rights reserved.
