Abstract
Efficient hydroxylation method at angular 8a position of 4a-aryl-trans -decahydroisoquinolines was described. By utilizing the transformation process, syntheses of 2-methyl- and -methoxyphenyl)-6-oxo-trans-decah ydroisoquinolines (13 and 17), the useful molecules as an opioid messa ge substructure, were attained. The key step in this transformation wa s N-protection of enamine intermediate by 2, 2,2-trichloroethoxycarbon yl chloride and subsequent epoxidation and hydride reduction.
