Abstract

An efficient CuI catalyst for the highly enantioselective cyclopropanation (>98% ee) of styrene with diazoacetic acid esters is obtained from the reaction of copper(I) trifluoromethanesulfonate with bis(dihydrooxazolyl)propane (1). The CuOTf‐1 complex is a helical coordination polymer air‐stable in the solid state, whose structure is not retained in solution. (Figure Presented.)
