Abstract:
Condensation reactions of 2,5-anhydro-aldehydo-D-xylose
and D-ribose, with malonic acid and it mono and diethyl esters, are studied.
Spectroscopic characteristics of the obtained tran-a
and b-glycofuranosylacrylic esters (threo and
erythro are compared, and these products are used in C-glycofuranosyls-dihydrouracils
synthesis.
