Stereoselective synthesis of enol acetates by the reaction of alkenylboronates with (diacetoxyiodo)benzene and sodium iodide
Abstract
Stereochemically pure (E)- and (Z
)-alk-1-en-1-yl acetates have been easily prepared by acetoxylation of the (Z
)- and (E
)-alk-1-en-1-ylboronic acids or their esters, respectively, with (diacetoxyiodo)benzene and sodium iodide, in reasonable yields.
