Synthesis of 1,4-enynes was performed via nickel-catalyzed cross-coupling of allylicalcohols with alkynylzinc reagents. The reaction features high regio- and E/Z-selectivity when aryl-substituted allylicalcohols were employed. The method also exhibits a wide scope of substrates and good compatibility of functional groups.
A novel and efficient Cu(OTf)2-catalyzed sp3–sp2 C–C bond formation reaction through the direct coupling of propargylicalcohols with terminal alkenes has been realized under mild conditions. The reaction is tolerant to air and is atom-economical, in accordance with the concept of modern green chemistry. The present protocol provides an attractive approach to a diverse range of 1,4-enynes in high to
