Downstream synthetic route of 83-87-4

As the paragraph descriping shows that 83-87-4 is playing an increasingly important role.

83-87-4, (3R,4S,5R,6R)-6-(Acetoxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetrayl tetraacetate is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

General procedure: A solution of peracetylated sugars (a-o) (1.28 mmol) in CH2Cl2 (7 mL) was slowly treated with33% (w/w) HBr in AcOH and was stirred to react for 3 h at room temperature. The reactionmixture was diluted with CH2Cl2 and washed with ice water, saturated NaHCO3 and watersuccessively. The resulting solution was dried over anhydrous Na2SO4 and then concentratedunder reduced pressure. The crude 1-bromo-peracetylated glycosyl donors (1a-1o) were obtainedand used without further purification., 83-87-4

As the paragraph descriping shows that 83-87-4 is playing an increasingly important role.
