A benzoheterocyclic derivative of the following formula [1]:
and pharmaceutically acceptable salts thereof, which show excellent anti-vasopressin activity, vasopressin agonistic activity and oxytocin antagonistic activity, and are useful as a vasopressin antagonist, vasopressin agonist or oxytocin antagonist.
The present work describes the discovery of novel series of (4,4-difluoro-1,2,3,4-tetrahydro-5H-1-benzazepine-5-ylidene)acetamide derivatives as arginine vasopressin (AVP) V(2) receptor agonists. By replacing the amide juncture in YM-35278 with a direct ring connection gave compound 10a, which acts as a V(2) receptor agonist. These studies provided the potent, orally active non-peptidic V(2) receptor

Novel Design of Nonpeptide AVP V<sub>2</sub> Receptor Agonists: Structural Requirements for an Agonist Having 1-(4-Aminobenzoyl)-2,3,4,5-tetrahydro-1<i>H</i>-1-benzazepine as a Template
The discovery of a series of nonpeptide arginine vasopressin V-2 receptor agonists is described. After identifying the aniline derivative 8 as our lead compound from the metabolites of compound 7 that showed antidiuretic activity by po administration to Brattleboro rats, improvements in the in vitro potency involving evaluations of the structural requirements for agonist action and optimizing the structure of the benzoyl moiety have been intensively undertaken. These studies led to compounds leg, 19a, and 23b,h,i that show patent; agonist activity for the V-2 receptor.

Benzo[b]azepines are important structural motifs for the pharmaceutical industry. However, their syntheses are usually lengthy, involving several steps, transition-metal catalysts, and/or harsh conditions. A novel, general, mild, and metal-free oxidative ringexpansion tandem reaction of hydroquinolines with TMSCHN2 as a versatile soft nucleophile to gain access to these valuable compounds in a simple and
苯并[ b ] a庚因是制药工业的重要结构基序。然而,它们的合成通常是冗长的,涉及多个步骤,过渡金属催化剂和/或苛刻的条件。提出了一种新颖,通用,温和且无金属的氢喹啉与TMSCHN 2作为通用型软亲核试剂的氧化扩环串联反应,以简单直接的方式获得这些有价值的化合物。
