New derivatives of A- and B-dithiophosphates of 2-bromo-2-deoxy sugars

Borowiecka J.

Polish Journal of Chemistry

1999

vol. 73 nr 5

793-798

New derivatives of 2-bromo-2deoxy hexopyranose, a and b-glycosyl dithiophosphates 6-11, were synthesized by three methods: (A) by glycosylation of alkyl salts 1-3 of phosphorodithio acids with a-1,2-D-gluco and a-1,2-D-manno dibromides 4,5; (B) by reaction of 4 or 5 with free phosphorodithio acids 12-14 activated by Lewis acid; (C) by addition of dithioacids 12-14 to 2-bromo-D-glucal 15.
