Regioselective cleavage of O-benzyl-N-arylamidoximes: synthesis of N-aryl amidines and amidoximes
摘要:
O-Benzyl-N-arylamidoximes have been regioselectively deprotected to provide either N-aryl amidines or amidoximes. As a result, the targeted compounds can now be prepared using palladium-catalyzed N-arylation chemistry. (C) 2002 Elsevier Science Ltd. All rights reserved.

Certain novel substituted imidazole 4-carboxamides are ligands of the human cholecystokinin receptor and, in particular, are selective ligands of the human cholecystokinin-1 receptor (CCK-1R). They are therefore useful for the treatment, control, or prevention of diseases and disorders responsive to the modulation of CCK-1R, such as obesity, and diabetes.

High-throughput screening revealed diaryl pyrazole 3 as a selective albeit modest cholecystokinin 1 receptor (CCK1R) agonist. SAR studies led to the discovery and optimization of a novel class of 1,2-diaryl imidazole carboxamides. Compound 44, which was pro. led extensively, showed good in vivo mouse gallbladder emptying (mGBE) and lean mouse overnight food intake (ONFI) reduction activities. (c) 2008 Elsevier Ltd.
