ABSTRACT
Aim:
To improve the synthesis for 2, 5-anhydro-3,4, 6-tri-O-benzyl-D-glucitol.Methods:
Dehydration of D-mannitol, followed by a reaction sequence of selective protection, benzylation, deprotection, tritylation, benzy-lation and removal of the trityl group, afforded the title compound.Results:
Based on the improvement of the reported synthetic route, 2,5-anhydro-3,4,6-tri-O-benzyl-D-glucitol was synthesized in seven steps from D-mannitol with a total yield of 8. 3% .Conclusion:
This new method features mild reaction conditions and facile work-up.
