Number: 548/424
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 > Tetracyclo ring system having the five-membered hetero ring as one of the cyclos > Two of the cyclos share at least three ring members, or a ring carbon is shared by three of the cyclos (e.g., bridged, peri-fused, etc.)
Description: Compounds wherein at least three ring members of one cyclo are ring members of an additional cyclo in the tetracyclo ring system, or wherein one ring carbon is a member of three of the cyclos in the tetracyclo ring system.
