Common Name

6'-ethyl-1,6-dimethoxy-10'-oxa-5'-azaspiro[indole-3,2'-tricyclo[5.3.1.0⁴,⁸]undecan]-2-one

Description

6'-Ethyl-1,6-dimethoxy-1,2-dihydro-10'-oxa-5'-azaspiro[indole-3,2'-tricyclo[5.3.1.0⁴,⁸]Undecane]-2-one belongs to the class of organic compounds known as gelsemium alkaloids. These are alkaloids with a structure that is based on the tetracyclic gelsemium skeleton. These alkaloids contain an oxindole function and a cage-like, hydroaromatic residue which is believed to arise from an intermediate related to anhydrovobasinediol by formation of a 6,20 bond and rearrangement to an oxindole. The major alkaloids in this group are related to Gelsemine; however, a smaller group, characterized by Gelsedine, lack the 6,20 bond, and have also lost C-21. 6'-ethyl-1,6-dimethoxy-10'-oxa-5'-azaspiro[indole-3,2'-tricyclo[5.3.1.0⁴,⁸]undecan]-2-one is found in Gelsemium elegans and Gelsemium sempervirens. 6'-Ethyl-1,6-dimethoxy-1,2-dihydro-10'-oxa-5'-azaspiro[indole-3,2'-tricyclo[5.3.1.0⁴,⁸]Undecane]-2-one is a very strong basic compound (based on its pKa).

Chemical Taxonomy

Description

Belongs to the class of organic compounds known as gelsemium alkaloids. These are alkaloids with a structure that is based on the tetracyclic gelsemium skeleton. These alkaloids contain an oxindole function and a cage-like, hydroaromatic residue which is believed to arise from an intermediate related to anhydrovobasinediol by formation of a 6,20 bond and rearrangement to an oxindole. The major alkaloids in this group are related to Gelsemine; however, a smaller group, characterized by Gelsedine, lack the 6,20 bond, and have also lost C-21.
