Notes:
Bromination of 2.3:4.5-di-O-isopropylidene-aldehydo-D-arabinose p-nitrophenyl-hydrazone affords the corresponding hydrazidic bromide. Similarly, chlorination of 3-O-benzyl-1,2-O-isopropylidene α-D-xylo-pentodialdo-1,4-furanose oxime leads to the corresponding hydroxamoyl chloride. These two compounds constitute useful new synthetic intermediates in carbohydrate chemistry. For example, they may be ethynylated, then cyclised respectively to pyrazolyl- and isoxazolyl-C-glycosides.
