Catalytic hydrogenation of phosphate enol esters present in branched chain dienepyranosides in a route to thromboxane analogs from d-galactose

Branched-chain conjugated dienepyranosides including vinyl phosphate esters were subjected to catalytic hydrogenation under different conditions. Heterogeneous catalysts led to isomerization products that were resistant to further hydrogenation. On the other hand, under homogeneous conditions, compl...
