Non-dehydrative pinacol rearrangement using a Lewis acid-trialkyl orthoester combined system

An efficient pinacol rearrangement mediated by trialkyl orthoformate has been developed. The reactions of various types of diols with a catalytic amount of a Lewis acid in the presence of an orthoester afforded the rearranged product in good yields via a cyclic orthoester intermediate. This combined system is applicable not only to cyclic and acyclic tri- and tetra- substituted diols but also to the diols having acid-sensitive acetals.

The Catalytic Pinacol Rearrangement of 1,2-Diols Using an Antimony(V)Salt

In the presence of a catalytic amount of antimony(V)chloride or antimony(V)salt generated from antimony(V)chloride and silver hexafluoroantimonate, the pinacol rearrangement of several 1,2-diols or their trimethylsilyl ethers proceeds smoothly to give the corresponding ketones in good yields.
