Bicyclo Ring System Having The Five-membered Hetero Ring As One Of The Cyclos Patents (Class 514/412)
- The ring nitrogen is bonded directly to nonshared ring carbons of the five-membered hetero ring (e.g., isoindole, etc.) (Class 514/416)
- Chalcogen bonded directly to ring carbon of the five-membered hetero ring (Class 514/418)
- C=X bonded directly or indirectly by an acyclic carbon or carbon chain to ring carbon of the five-membered hetero ring (e.g., tryptophan, etc.) (X is chalcogen) (Class 514/419)
