Angustine Chemical Properties,Uses,Production

Description

A synthesis of angustine has recently been reported. Ethyl oxalate is condensed with 4-methyl-5-vinylinicotinonitrile followed by condensation of the lactone thus produced with tryptamine. Hydrolysis and then cyclization of the product yields angustine.

Definition

ChEBI: Angustine is a member of beta-carbolines.
