✦ Synopsis

Regio-and Stereoselective Vinylic Substitution Reactions of α-Haloenyne Sulfones.

-A variety of alcoholates undergoes a nucleophilic vinylic substitution reaction with (E)-α-haloenyne sulfones such as (I) to yield the corresponding alkoxyenyne sulfones highly regioselectively. Attempted isomerization of the propynyl ether (Vc) to allenes by basic treatment results in the formation of the furan derivatives (VI). -(YOSHIMATSU, M.;
