Class Information
Number: 540/105
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 > Cyclopentanohydrophenanthrene ring system containing > Hetero ring attached directly to the cyclopentanohydrophenanthrene ring system by nonionic bonding > The hetero ring contains -c(=x)-o-, wherein x is chalcogen, as part of the ring (e.g., lactones, etc.) > Chalcogen bonded directly at the 14-position of the cyclopentanohydrophenanthrene ring system or double bond in the d ring (e.g., cardenolides, etc.)
Description: Compounds wherein chalcogen (i.e., oxygen, sulfur, selenium or tellurium) is bonded directly at the 14-position of the cyclopentanohydrophenanthrene ring system or the D ring of the cyclopentanohydrophenanthrene ring system contains a double bond.
