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.

The invention concerns the use of PDE2 inhibitors for treating disorders of the central and peripheral nervous system, a method for therapeutic treatment by administering to an animal said inhibitors. More specifically, the invention concerns novel benzodiazepinone derivatives and their uses in therapeutics more particularly for treating pathologies involving activity of a cyclic nucleotide phosphodiesterase type 2. The invention also concerns methods for preparing same and novel synthesis intermediates.

Pharmacophoric comparison between papaverine and tofisopam led to identify three new series of micro- to sub-micromolar inhibitors of phosphodiesterase-4, including 7,8-dialkoxy-2,3-benzodiazepin-4-one derivatives, 7,8-dialkoxy-1,4-benzodiazepin-2-one derivatives, and dialkoxybenzophenone derivatives.
