Codeine Analogues. Synthesis of 4a-(2,3-Dimethoxyphenyl)decahydroisoquinolines and Octahydro-1H-benzopyranoisoquinolines

Extension of our methods for the synthesis of phenyl- and (m-methoxyphenyl)decahydroisoquinolines to the 2,3-dimethoxyphenyl series is presented.Surprisingly, direct extrapolation of the previous methodology was frequently not possible, as the dimethoxyph
