Number: 548/439
Name: Organic compounds -- part of the class 532-570 series > Organic compounds (class 532, subclass 1) > Heterocyclic carbon compounds containing a hetero ring having chalcogen (i.e., oxygen, sulfur, selenium, or tellurium) or nitrogen as the only ring hetero atoms (class 540, subclass 1) > Hetero ring is five-membered consisting of one nitrogen and four carbons (e.g., halopyrrolidines, etc.) > Polycyclo ring system having the five-membered hetero ring as one of the cyclos > Tricyclo ring system having the five-membered hetero ring as one of the cyclos > The five-membered hetero ring shares ring carbons with two carbocyclic rings (e.g., tetrahydrocarbazoles, etc.)
Description: Compounds wherein each of the two carbocyclic rings in the tricyclo ring system share ring carbons with the five-membered hetero ring.
