S. Hosztafi et S. Makleit, SYNTHESIS OF NEW APOMORPHINE DERIVATIVES CONTAINING HALOGEN (CL AND BR) IN RING-D, Synthetic communications, 26(21), 1996, pp. 3909-3918
A series of 8-halogen- (Cl,Br)-substituted apocodeines was prepared by
the rearrangement of the corresponding 1-halogen-substituted codeines
. O-demethylation of the apocodeines yielded the 8-halogenoapomorphine
s. 8-bromosubstituted morphothebaine derivatives have been convenientl
y prepared by direct bromination.
