As in the case of 1-benzyl congeners, LTA oxidation in CHaCF of ( )-1,2,3,4-tetrahydro-7-methoxy-1 -(3,4-dimethoxyphenethyl)-2-methyl-isoquinolin-6-ol (172) was found to give quantitatively o-quinol acetate 175, the structure of which was readily determined by spectroscopy. However, treatment of the unpurified o-quinol acetate 175 with acetic anhydride containing concentrated sulfuric acid produced ( )-2-acetoxy-1,10,11-trimethoxy-C-homoaporphine (178) in 25.3% yield, accompanied by a comparable amount of a biphenyl compound (181) (58).
