Yield:2835-06-5 95%

Reaction Conditions:

with ammonium formate;Cp*IrCl(N-(4'-methoxyphenyl)-2-pyridinecarboxamide) complex in methanol at 60; for 1.5 h;Inert atmosphere;Schlenk tube;

Steps:

28 Synthesis of DL-2-phenylglycine
Examples 28 Synthesis of DL-2-phenylglycine 751 mg (5.0 mmol) of benzoyl formate (MW: 150.13), 946 mg (15.0 mmol) of ammonium formate (MW: 63.06), and 5.90 mg (0.01 mmol, S/C=500) of the iridium catalyst Ir-7 (MW: 590.13) were introduced in a 20-mL Schlenk tube and subjected to argon-gas replacement. 5 mL of dehydrated methanol was added and the mixture was stirred while heating at 60° C. for 1.5 hr. After distillation of the solvent, a crystal was collected by filtration, washed with methanol, dried under reduced pressure to give 718 mg of DL-2-phenylglycine (95% yield).
