Stereoselective Synthesis of Trisubstituted Vinyl Bromides by Addition of Alkynes to Oxocarbenium Ions
We have developed an efficient method for the synthesis of (E)-trisubstituted vinyl bromides via a Friedel–Crafts-type addition of alkynes to oxocarbenium ions formed in situ from acetals. The success of this reaction relies on identification of MgBr(2)·OEt(2) as both a Lewis acid promoter and bromi...
