Radical reaction of p-quinolacetate (8b) of N-trifluroroacetyl-1-(2-iodoveratryl)methyl-1, 2, 3, 4-tetrahydro-7-methoxyisoquinolin-6-ol (7b) using tributyltin hydride gave the corresponding noraporphine (9)(45 %), while that of the bromo congener (8a) failed. Similar reaction of 8b using tris(trimethylsilyl)silane improved the yield (75 %) of 9.
