Abstract
A new class of anti-spasmodic thioester compounds having a heterocyclic ring containing the nitrogen atom of a secondary or tertiary amine or a bicycloheterocyclic ring system containing the nitrogen atom of a secondary or tertiary amine. These compounds have the general formula I ##STR1## wherein: n is an integer from 0 to 2; R.sub.1 is aryl or cycloalkyl; R.sub.2 is hydrogen or hydroxyl; and R.sub.3 is selected from the group consisting of heterocyclic containing the nitrogen atom of a secondary or tertiary amine to which an alkyl group having from 0 to 3 carbon atoms is bonded and no other hetero atoms are present in the ring structure; heterocyclic containing the nitrogen atom of a secondary or tertiary amine to which an alkyl group having from 0 to 3 carbon atoms is bonded and one or more hetero atoms selected from the group consisting of N, O and S are present in the ring structure; bicycloheterocyclic ring system containing the nitrogen atom of a secondary or tertiary amine to which an alkyl group having from 0 to 3 carbon atoms is bonded and no other hetero atoms are present in the ring system; and bicycloheterocyclic ring system containing the nitrogen atom of a secondary or tertiary amine to which an alkyl group having from 0 to 3 carbon atoms is bonded and one or more hetero atoms selected from the group consisting of N, O and S are present in the ring system.
