Class Information
Number: 548/438
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 > A ring carbon is shared by three of the cyclos (e.g., peri-fused, etc.) > Benzene ring, which is not a cyclo in the tricyclo ring system, bonded directly to ring carbon of the five-membered hetero ring
Description: Compounds wherein a benzene ring, which is not a cyclo in the tricyclo ring system, is bonded directly to ring carbon of the five-membered hetero ring.
