^aGeneral conditions: 0.7 mmol BocNH₂, 0.5 mmol carbonate, 0.02 mmol 1d, and 10 µL dodecane in 0.5 mL ether. Results are an average of two runs.

^bDetermined by NMR analysis of the crude reaction mixture or isolation.

^cIsolated yield of branched product.

^dDetermined by chiral HPLC analysis, see Supporting Information for details.

^eTHF was used as solvent.

^fK₃PO₄ (0.25 mmol) was added.

^gReaction was run at 30 °C.
