PROCESS FOR THE SYNTHESIS OF BASE ADDITION SALTS OF 2,3-0-ISOPROPYLIDENE-1-0-SUBSTITUTED-5,6-DIDEOXY-5-N- (4-(2-HYDROXY-2-OXOETHYL)-PHENYLAMINOCARBONYL) AMINO-L-GULOFURANOSIDES

摘要

The present invention relates to processes for the synthesis of base addition salts of particular ß-L- gulofuranosides. More specifically, the invention relates to synthetic processes for making base addition salts of 2,3-O-isopropylidene-1-O-substituted-5,6-dideoxy-5-N-[4-(2-hydroxy-2-oxoethy)-phenylaminocarbony]amino-ß-L-gulofuranosides.
