evaluated for antihypertensive activity in the spontaneously hypertensive rat (SHR). The basic ring system was prepared in one step by condensation of dilithiated (tert-butoxycarbonyl)aniline (3) with (tert-butoxycarbonyl)piperidinone. Deprotection afforded 6, which was condensed with expoxides or alkyl halides to furnish the title compounds. The most active compound was dl-erythro-4'-[2-(1,4-benzodi
制备了一系列4'-取代的螺[4H-3,1-苯并恶嗪-4,4'-哌啶] -2(1H)-酮,并评估了自发性高血压大鼠(SHR)的降压活性。通过将二锂化的(叔丁氧羰基)苯胺(3)与(叔丁氧羰基)哌啶酮缩合来制备碱性环体系。脱保护得到6,其与过氧化物或烷基卤化物缩合以提供标题化合物。活性最高的化合物是dl-erythro-4'-[2-(1,4-苯并二恶烷-2-基)-2-羟乙基]螺[4H-3,1-苯并恶嗪-4,4'-哌啶] -2为了阐明系列中的结构-活性关系,进行了(1H)-一个(9)以及该化合物的各种修饰。初步迹象表明9可能由中央和外围机制共同起作用。
