Regioselectivity in the nickel-catalysed coupling of cyclic carbonates of but-3-ene-1,2-diols with organoborates
Abstract
The regioselectivity of nickel-catalysed coupling of but-3-ene-1,2-diol cyclic carbonates 1 and organoborates 3 is examined, in which an ester or olefin directs the coupling site to afford conjugated products.
