aSyntheses of catalysts and diazo compounds are summarized in ESI;15 reactions were carried out at room temperature for 72 h using [Co(P3)] under N2; isolated yields; the trans : cis diastereomeric ratios were determined by 1H-NMR; enantiomeric excesses were determined by chiral HPLC.

b[2S,3R] absolute configuration determined by anomalous-dispersion effects in X-ray diffraction measurements on a crystal.

c5 mol% catalyst used.

dPhF used as solvent.
