S. Hosztafi et S. Makleit, SYNTHESIS OF NEW MORPHINE DERIVATIVES CONTAINING HALOGEN IN THE AROMATIC RING, Synthetic communications, 24(21), 1994, pp. 3031-3045
The C-1 halogenated (brominated and chlorinated) analogues of morphine
, codeine and their dihydro derivatives have been synthesized by means
of known and new procedures. Hitherto unknown N-demethylation of thes
e derivatives has also been explored, and several new N-demethyl-N-sub
stituted analogues (allyl, n-propyl) have been prepared with the aim o
f contributing to a better understanding of certain details of the str
ucture-activity relationships of the morphine alkaloids.
