Class Information
Number: 546/39
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 > Hexacyclo ring system having the six-membered hetero ring as one of the cyclos > Two of the cyclos share at least three ring members (e.g., etheno morphides, etc.)
Description: Compounds wherein at least three ring members of one cyclo are ring members of an additional cyclo in the hexacyclo ring system (i.e., bridged).
