Yield:150-30-1 62%

Reaction Conditions:

with [Cp*Ir(N-phenyl-2-pyridinecarboxamidate)Cl];ammsnium formate in methanol at 37; for 6 h;chemoselective reaction;

Steps:

General Procedure for Reductive Amination of α-Ketoacids

General procedure: α-Ketoacid (0.2 mmol) and Ir1 (1 mol%) were added to a 1.5-dram vial equipped with amagnetic stir bar in methanol (1 mL). Solid HCOONH4 (2 mmol, 10 equiv.) was added to thevial and the solution was stirred at 37 °C for 6 h.
