Abstract: Firstly, 3,4,5,6,7-penta-O-benzyl-D-manno-hept-1-enitol was prepared from 2,3,4,5,6-penta-O-benzyl-D-mannose via Wittig reaction(yield 88%). The olefinated sugar was dihudroxylated to yield 3,4,5,6,7-penta-O-benzyl-D-mannoheptol(yield 65%) with the presence of phenyliodine(Ⅲ) diacetate(PIDA)/LiBr. Finally, D-mannoheptol was synthesized through debenzylation(yield 90%). The overall yield was about 51%. The method had the advantages of convenience and environmental friendly, which provided a new approach for the synthesis of such rare alditol.

Key words: D-mannoheptol, olefinated sugar, PIDA, dihydroxylated reaction
