Studies on the syntheses of heterocyclic compounds. Part CDXLVI. Total photolytic synthesis of (±)-androcymbine and (±)-multifloramine
Abstract
Photolysis of 1-(2-bromo-4-hydroxy-3,5-dimethoxyphenethyl)-1,2,3,4-tetrahydro-7-hydroxy-6-methoxy-2-methylisoquinoline (8) in the presence of sodium iodide gave (±)-androcymbine (1). When the photolysis was done without sodium iodide, it afforded only multifloramine (10).
