DEFINITION

Classification: 546/144

Unsaturated ring attached directly to the six-membered hetero ring by nonionic bonding:

(under subclass 139) Compounds wherein an unsaturated ring, i.e., a ring having at least one double bond between ring members, is attached directly to the six-membered hetero ring by nonionic bonding.

(1) Note. The term "unsaturated ring" as used herein does not refer to the six-membered carbocyclic ring of the isoquinoline ring system but rather to an additional unsaturated ring which is attached directly to the six-membered ring.
