New derivatives of 2-bromo-2-deoxy hexopyranose, alpha- and beta-glycosyl d
ithiophosphates 6-11, were synthesized by three methods: (A) by glycosylati
on of alkyl salts 1-3 of phosphorodithio acids with alpha-1,2-D-gluco and a
lpha-1,2-D-manno dibromides 4, 5; (B) by reaction of 4 or 5 with free phosp
horodithio acids 12-14 activated by Lewis acid; (C) by addition of dithioac
ids 12-14 to 2-bromo-D-glucal 15.
