Class Information
Number: 548/458
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 five-membered consisting of one nitrogen and four carbons (e.g., halopyrrolidines, etc.) > Polycyclo ring system having the five-membered hetero ring as one of the cyclos > Bicyclo ring system having the five-membered hetero ring as one of the cyclos (e.g., octahydroindoles, etc.) > Additional polycyclo heterocyclic ring system attached directly or indirectly to the bicyclo ring system by nonionic bonding > The additional polycyclo ring system includes a five-membered nitrogen containing hetero ring > Ring carbon of one of the five-membered hetero rings is bonded directly to ring carbon of the other (e.g., indigo dyes, etc.) > By a single bond (e.g., leuco indigo, etc.)
Description: Compounds wherein the ring carbons are bonded to each other by a single bond.
