generated efficiently by a site-selective hydroalumination of an alkyne with dibal-H. The desired products, containing a quaternarycarbonstereogeniccenter, are obtained in 48-95% yield after purification and in 89:11 to >98:2 enantiomer ratio (er). The vinylsilane moiety within the products can be functionalized to afford acyl, vinyliodide, or desilylated alkenes in 67% to >98% yield and with >90% retention
