Class Information
Number: 546/44
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.)
Description: Compounds wherein one of the cyclos of the pentacyclo ring system is a five-membered hetero ring which contains ring chalcogen (i.e., oxygen, sulfur, selenium, or tellurium).
