Class Information
Number: 548/508
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.) > The bicyclo ring system consists of the five-membered hetero ring and a benzene ring (e.g., indole, etc.) > Processes of forming the bicyclo ring system by cyclization (e.g., forming indole from o-ethyl aniline, etc.)
Description: Processes wherein the bicyclo ring system is formed by ring closure.
