A highly efficient anti-SE2′ electrophilic fluorination of enantioenriched allylsilanes a subsequent dihydroxylation of the resulting allylic fluorides were used as key steps for the synthesis of three fluorinated carbohydrate analogues, 1,5-di-O-benzyl-2-deoxy-2-fluoro-d-glucitol, 2,6-di-O-benzyl-5-deoxy-5-fluoro-l-glucitol and 1,5-di-O-benzyl-2-deoxy-2-fluoro-d-mannitol. A new catalytic asymmetric route to 1-benzyloxy-4-trimethylsilyl-but-3-yn-2-ol, a common precursor to two advanced allylsilanes, is also described featuring a Noyori asymmetric transfer hydrogenation reaction.

A practical method for the synthesis of several useful polyhydroxylated chiral building blocks has been developed.The key reaction is the kinetic resolution of (E)-1-trimethylsilyl-4-alkoxy-1-buten-3-ol or (E)-1-trimethylsilyl-5-alkoxy-1-penten-3-ol using the Sharpless asymmetric epoxidation reaction.
