[reaction: see text] The synthesis of various tetrasubstituted alkenes and dienes in a regio- and stereocontrolled manner is described. This three-component coupling strategy involves the addition of Grignard reagents to propargyl alcohols followed by palladium(0)-mediated cross-coupling with aryl or vinyl halides. This protocol has been applied to the synthesis of (Z)-Tamoxifen and related mimics
