Abstract

Reaction of “9.10-Dehydro-indolinocodeine-methoperchlorate” (4) with sodium methoxide solution yields thedes-base (7R)-7-methoxyneopine-methine (5 a). Its structure was established on the basis of spectroscopic methods.Hofmann degradation of5 a affords the so far unknown 3.6-dimethoxy-phenanthro[4.5—bcd]furane (7).
