The synthesis of N-substituted 1,7,7-trimethyl-2-piperidinobicyclo[2.2.1]hept-2-ene 3 carboxamides (II) by reaction of 1,7,7-trimethyl-2-piperidinobicyclo[2.2.1]hept-2-ene (I) with alkyl and aryl isocyanates, as well as the alkaline hydrolysis of (II) to N-substituted 1,7,7-trimethylbicyclo[2.2.1]heptan-2-one 3 carboxamides (III), are described. A number of compounds (II) and (III) showed strong hypotensive and bradycardiac activities in rats, as well as weak infiltration anesthesia and antiarrhythmic activity in mice. Antiacetylcholine activity in vitro is also reported.
