Class Information
Number: 549/394
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) > Oxygen containing hetero ring (e.g., dioxirane, etc.) > The hetero ring is six-membered > Polycyclo ring system having the hetero ring as one of the cyclos > Tricyclo ring system having the hetero ring as one of the cyclos > The tricyclo ring system consists of three six-membered cyclos (e.g., xanthene, etc.) > Nitrogen bonded directly to the tricyclo ring system
Description: Compounds in which nitrogen is bonded directly to the tricyclo ring system.
