Copper-Catalyzed Regioselective and Stereoselective Coupling of Grignard Reagents with Pent-1-en-4-yn-3-yl Benzoates: A Shortcut to (<i>Z</i>)<i>-</i>1,5-Disubstituted Pent-3-en-1-ynes from Accessible Starting Materials
Copper-catalyzed coupling of Grignardreagents with pent-1-en-4-yn-3-yl benzoates occurs regioselectively at the terminal alkenyl carbon rather than the alkynyl site, leading to the stereoselective formation of unexpected (Z)-1,5-disubstituted pent-3-en-1-ynes without generation of the initially expected alkenyl allene products. By using easily accessible starting materials, this reaction can provide

Opticallyactive tert-allylic alcohols constitute important and often challenging targets in organic synthesis. In this work, we employed a β-sulfinyl moiety as a remote chiral auxiliary to effect asymmetric 1,2-addition of aryl Grignardreagents to enones to form a variety of opticallyactive tert-allylic alcohols. The absolute configuration of a representative alcohol product was determined by X-ray
