Number: 544/117
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.) > Six-membered hetero ring consists of oxygen, nitrogen and carbon (e.g., 1,2-oxazines, etc) > 1,4-oxazines > Morpholines (i.e., fully hydrogenated 1,4-oxazines > Additional nitrogen containing hetero ring (e.g., thiazetidine, etc.) > Diazine ring > The diazine ring is one of the cyclos in a polycyclo ring system > The diazine ring is one of the cyclos in a bicyclo ring system > Three or more ring hetero atoms in the bicyclo ring system
Description: Compounds wherein the bicyclo ring system contains at least one ring hetero atom in addition to the two ring nitrogens of the additional six-membered hetero ring.
