Class Information
Number: 544/284
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 having two or more ring hetero atoms of which at least one is nitrogen (e.g., selenazines, etc.) > The six-membered hetero ring consists of two nitrogens and four carbons (e.g., 1,2-diazines, etc.) > 1,3-diazines > Polycyclo ring system having the diazine ring as one of the cyclos > Bicyclo ring system having the diazine ring as one of the cyclos > The other cyclo in the bicyclo ring system is a benzene ring (e.g., quinazoline, etc.) > Additional nitrogen containing unsaturated hetero ring (e.g., thiazole, etc.)
Description: Compounds having, in addition to the bicyclo ring system, a hetero ring which has at least one double bond between ring members and at least one ring nitrogen.
