摘要

A series of 4'-substituted spiro [4H-3, l-benzoxazine-4, 4'-piperidin]-2 (1H)-ones was prepared and evaluated for antihypertensive activity in the spontaneously hypertensive rat (SHR). The basic ring system was prepared in one step by condensation of dilithiated (tert- butoxycarbony1) aniline (3) with (tert-butoxycarbony1) piperidinone. Deprotection afforded 6, which was condensed with expoxides or alkyl halides to furnish the title compounds. ...
