A simple, efficient, stereoselective, and highly regioselective method for the synthesis of beta-hydroxyacetylenes by the direct opening of 1,2-epoxides with lithium acetylides in anhydrous THF, in the presence of metal salts, is described. This new method appears to be competitive and alternative to the other methods previously reported.

Abstract
A simple, efficient, stereoselective, and highly regioselective method for the synthesis of beta-hydroxyacetylenes by the direct opening of 1,2-epoxides with lithium acetylides in anhydrous THF, in the presence of metal salts, is described. This new method appears to be competitive and alternative to the other methods previously reported.File in questo prodotto:
