Payne and Williams found that maleic, fumaric, and crotonic acid are very resistant to attack by peracetic or perbenzoic acid but are converted into their epoxides in yields of 77, 50, and 50% by hydrogen peroxide-sodium tungstate at pH 4-5.5. Addition of the peroxide initiates an exothermal reaction which is... [Pg.971]

A synthesis of 6-deoxy-6-hydroxyamino- -D-glucopyranoside from the corresponding 6-aminosugar by the sequence of oxidation with hydrogen peroxide - sodium tungstate to the oxime followed by cyanoborohydride reduction was copied in a synthesis of the pseudo-trisaccharides 6 -N-hydroxykanamycin A and 6 -N-hydroxydibekacin from the corresponding parent antibiotics, but the products were...
