Abstract
A Friedel-Crafts alkylation of pyrrole was developed to afford the β,γ-unsaturated α-hydroxy esters bearing a quaternary stereogenic center with good enantioselectivities and yields. This protocol represents the first report of 1,2-addition of Friedel-Crafts alkylation of pyrrole to β,γ-unsaturated α-ketoesters.
