title: N'-acyl-N,N-(1,3,3-trimethylbicyclo [2.2.1]hept-2-ylidene)benzamidines with hypotensive activity.
abstract: The reaction of fenchone nitrimine (I) with benzamidine gave in good yield N,N-(1,3,3-trimethylbicyclo [2.2.1]hept-2-ylidene)benzamidine (II), which by acylation afforded N'-acyl-N,N-(1,3,3-trimethylbicyclo[2.2.1]hept-2-ylidene)benzam idines (III a-f) in excellent yields. Compounds (III) showed a moderate hypotensive activity in rats and a weak local anesthetic activity by infiltration in mice. Effects on heart rate and antiarrhythmic activity in rats are also reported.
