Regio- and stereoselective synthesis of 1,4-enynes by iron-catalysed Suzuki–Miyaura coupling of propargyl electrophiles under ligand-free condition

Abstract

The first iron-catalysed cross coupling of propargyl electrophiles with lithium alkenylborates has been developed. Various propargyl electrophiles can be cross-coupled with lithium (E)- or (Z)-alkenylborates in a stereospecific manner to give the corresponding 1,4-enynes in good to excellent yields. The reaction features high SN2-type regioselectivity and functional group compatibility.
