Class Information
Number: 549/315
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) > Oxygen containing hetero ring (e.g., dioxirane, etc.) > Lactones (i.e., -c(=x)o-, wherein x is chalcogen, is part of the hetero ring) > The lactone ring is five-membered > Additional chalcogen bonded directly to the lactone ring > At least two additional chalcogens bonded directly to the lactone ring > Double bond between ring members of the lactone ring or chalcogen double bonded directly at the 3- or 4-position of the lactone ring (e.g., ascorbic acid, etc.)
Description: Compounds wherein there is a double bond between ring members of the lactone ring, or chalcogen (i,e., oxygen, sulfur, selenium, or tellurium) is double bonded directly at the 3- or 4- position of the lactone ring.
