Cyclic and acyclic phosphate esters of some 1,2-O-isopropylidene-α-D-pentofuranosesWhen treated with monophenyl phosphorodichloridate, 1,2-O-isopropylidene-α-D-xylofuranose gave the two possible, isolable isomers of the corresponding 3,5-cylic phenylphosphate. Upon phosphorylation of the same sugar derivative using bis (2,2,2-trichloroethyl) phosphorochloridate only one isomer was formed. The same situation obtained when preparing 1,2-O-isopropylidene-α-D-ribofuranose-3,5-cyclic phenylphosphate. The synthesis of a new kind of sugar phosphate with a branched-chain unsaturated sugar moiety namely the trans-3-deoxy-3-C-cyanomethylene-1,2-O-isopropylidene-D-erytho-pentofuranose 5-bis(2,2,2-trichloroethyl) phosphate is also described.
