Class Information
Number: 540/325
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 > Hetero ring is four-membered containing nitrogen and having chalcogen double bonded directly to a ring carbon which is adjacent to the ring nitrogen > Polycyclo ring system containing the hetero ring as one of the cyclos > The ring nitrogen is shared by a five-membered ring > The five-membered ring contains an additional hetero atom > 1-thia-4-aza-bicyclo(3.2.0)hep-tane (including unsaturated; e.g., penam, etc.) > Having -c(=x)-, wherein x is chalcogen, bonded directly at the 3-position of the bicyclo ring system > Nitrogen bonded directly at the 6-position of the bicyclo ring system > Having -c(=x)-, wherein x is chalcogen, single bonded directly to the nitrogen (e.g., penicillin f, etc.) > The nitrogen is part of a hetero ring
Description: Compounds in which the nitrogen at the 6-position is part of a hetero ring.
