Regioselective Synthesis of 5-Endo,6-Endo-Dihydroxy-7-Oxabicyclo[2.2.1]Heptan-2-One with Differential Protection of the Diol Group

The introduction of two hydroxy groups with differential protection at the endo positions of C(5) and C(6) of the ''naked sugars of the first generation'' has been achieved by seleno-Pummerer rearrangement of 5-endo-hydroxy-6-exa-phenylseleno-7-oxabicyclo[2.2.1]heptan-2-one derivatives followed by deselenation with Bu(3)SnH.
