Catalytic Enantioselective Cr-Mediated Propargylation: Application to Halichondrin Synthesis
[Image: see text] A catalytic enantioselective propargylation in the presence of 10 mol % Cr-catalyst prepared from Cr(III) bromide and (R)-sulfonamide E furnishes homopropargyl alcohol 8 in 78% yield with 90% ee. Coupled with the workup based on Amano-lipase, this method provides a practical synthe...
