^aReaction conditions: diazoketone and PhCO₂Ag (10 mol%) in CH₂Cl₂ (0.2 M).

^b20 mol% of PhCO₂Ag was used.

^cee was determined by ¹⁹F NMR (Mosher ester derivatives); only one isomer was observed.

^dAg₂O (10 mol%) and C₂H₄Cl₂ (0.2 M) were used.

^edr was determined by ¹H NMR; only one isomer was observed.
