Class Information
Number: 546/68
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 > Tetracyclo ring system having the six-membered hetero ring as one of the cyclos > Plural ring hetero atoms in the tetracyclo ring system (e.g., acronycines, etc.) > Ring carbon is shared by three of the cyclos > The three cyclos consist of two carbocyclic rings and a five-membered hetero ring which includes a ring nitrogen (e.g., ergolines, etc.) > Chalcogen or nitrogen bonded directly to ring carbon of the six-membered hetero ring
Description: Compounds wherein chalcogen (i.e., oxygen, sulfur, selenium, or tellurium) or nitrogen is bonded directly to a ring carbon of the six-membered hetero ring.
