Class Information
Number: 549/437
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.) > The hetero ring is five-membered > Plural ring oxygens in the hetero ring > Polycyclo ring system having the hetero ring as one of the cyclos > Bicyclo ring system having the hetero ring as one of the cyclos > Acyclic chalcogen bonded directly to the bicyclo ring system
Description: Compounds wherein the acyclic chalcogen (i.e., oxygen, sulfur, selenium, or tellurium) is bonded directly to the bicyclo ring system.
