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 > 1,4-diazine ring
Description: Compounds in which the nitrogen atoms of the additional six-membered hetero ring are in the 1, 4-positions.
