D-Mannofuranosyl fluoride

Tetrabenzoyl 2,3,5,6-Tetra-O-benzoyl-a-D-mannofuranosyl fluoride C34H27FO9 598.58 Cryst. (Et20). Mp 90-91°. [a]g -115.6 (c, 2 in CHCI3). [Pg.698]

Protected P-thioglycosides have been converted rapidly and efficiently by dimethyl (methylthio)sulfonium tetrafluoroboiate into the corresponding a-glycosyl fluorides, while tetra-0-acetyl-glucopyranosyl fluoride has been rearranged in anhydrous HF to the 2,3 5,6 diacetoxonium ion of a-D-mannofuranosyl fluoride. The synthesis of 3,4,5-tri-<9-benzyl-7-0-r-butyldiphenylsilyl-l-0-(2,2,2-triphenyl)ethyl-D-g/Mco-2-heptulopyranosyl fluoride has been described. ... [Pg.103]

Tri-C -acetyl-2-0-raethyl-j8-D-mannofuranosyl fluoride (40%) and the corresponding a-anomer (11%) were obtained following prolonged treatment of... [Pg.48]
