    • Representative Procedure for the Synthesis of 2-Oxazolidinones 4a-j A solution of (1S,2R)-norephedrine (3a, 210 mg, 1.39 mmol) and tetramethylphenylguanidine (290 mg, 1.52 mmol, 110 mol, in anhyd MeCN (10 mL) was cooled to -40°C with a dry ice-acetone bath. Carbon dioxide was slowly bubbled through the solution for 5 min, and then diphenylphosphoryl azide (DPPA, 0.30 mL, 1.39 mmol, 100 mol, was added dropwise. Carbon dioxide bubbling was maintained for a further 15 min, and the reaction mixture was stirred overnight while it was slowly allowed to reach 20°C. The resulting solution was concentrated almost to dryness. The residue was dissolved in CHCl3 (30 mL) and washed with a 10% Na 2CO3 (previously saturated with NaCl) solution (1x, The aqueous layer was extracted with CHCl3. The combined organic layers were washed with 1 M HCl (previously saturated with NaCl) solution 1x, The aqueous layer was furth
