6-Substituted 6-deoxy-L-galactose (L-fucose) derivatives were synthesized as potential antimetabolites of L-fucose. The cytotoxic effects of these compounds were evaluated on P388 leukemia cells in culture. The L-fucose analogues which showed the most potent growth inhibition were the sulfonyl ester, bromo, and iodo derivatives; since these compounds were all capable of alkylation, it is conceivable

prepared by the reaction of thebaine with N-bromosuccinimide and N-chlorosuccinimide, respectively. These 14 beta-substituted codeine and codeinones were O-demethylated to the corresponding morphine analogues with boron tribromide. With the exception of 14 beta-nitromorphinone, which was weak in activity, all the other 14 beta-substituted morphine derivatives were approximately equal in potency to normorphine
