Class Information
Number: 546/53
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 > Plural ring hetero atoms in the pentacyclo ring system > Two ring nitrogens in the pentacyclo ring system (e.g., quinacridones, etc.) > Ring nitrogen is shared by two of the cyclos (e.g., yohimbanes, etc.) > Having -c(=x)-, wherein x is chalcogen, bonded directly to ring carbon of the pentacyclo ring system and also bonded directly to chalcogen or nitrogen
Description: Compounds in which a group, wherein X is chalcogen (i.e., oxygen, sulfur, selenium, or tellurium) is bonded directly both to a ring carbon of the pentacyclo ring system and to a chalcogen or nitrogen atom.
