摘要：

Styrene and diazo esters react in the presence of copper(II) trifluoromethanesulfonate (1 mol%) and (1S,2S)-N,N'-di(mesitylmethyl)-1,2-diphenyl-1,2-ethanediamine (2 - 3 mol%) to give 2-phenyl-1-cyclopropanecarboxylates in good to excellent optical yields. This reaction has been applied to the synthesis of chrythanthemic acid.
