Abstract
Spiro(1,2,3,4-tetrahydroquinazoline -4,4'-imidazolidine) derivs. of formula (I) and their salts are new. In (I), R = H or 1-5C alkyl; R1 = 1-5C alkyl, opt. substd. Ph or aralkyl; R2-R5 = H, halogen, 1-5C alkyl, 1-5C alkoxy, (2-6C)alkoxycarbonyl or (2-6C)alkoxycarbonyl (2-6C)alkenyl; or 2 adjacent substituents R2-R5 = OCH2O; and the other 2 substituents = H. - Intermediates of formula (II) are new. X = CONH2 or C(=NH)SR6; R6 = 1-5C alkyl.
