Class Information
Number: 546/45
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 six-membered consisting of one nitrogen and five carbons > Polycyclo ring system having the six-membered hetero ring as one of the cyclos > Pentacyclo ring system having the six-membered hetero ring as one of the cyclos > Two of the cyclos share at least three ring members (i.e., bridged) > One of the five cyclos is five-membered and includes ring chalcogen (e.g., codeine, morphine, etc.) > Nitrogen or divalent chalcogen double bonded directly to carbocyclic ring of the pentacyclo ring system (e.g., morphinones, etc.)
Description: Compounds wherein a nitrogen atom or a divalent chalcogen (i.e., oxygen, sulfur, selenium, or tellurium) is attached directly by a double bond to a carbocyclic ring of the pentacyclo ring system.
