摘要

Abstract A simple, efficient, stereoselective, and highly regioselective method for the synthesis of β-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.
