DEFINITION

Classification: 546/149

Unsaturated carbocyclic ring attached indirectly to the six-membered hetero ring through an acyclic hydrocarbon chain:

(under subclass 139) Compounds wherein an unsaturated carbocyclic ring, i.e., a ring consisting of carbon atoms and having at least one double bond between ring members, is attached indirectly to the six-membered hetero ring of the isoquinoline ring system through an acyclic hydrocarbon chain, i.e., a chain consisting of carbon and hydrogen atoms.
