(4S,5R)-4-amino-5-ethoxyoxolan-2-one

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a suspension of (2R, 3S)-(2-Ethoxy-5-oxo-tetrahydro-furan-3-yl)-carbamic acid benzyl ester (0.22 g, 0.86 mmol) in Ethyl acetate (25 mL) at room temperature was added 10 mol % Pd/C (˜0.03 g). The reaction flask was purged between H2 (1atm) and vacuum three times before stirring under H2 (1atm) at room temperature. After stirring at room temperature for 3 hrs, the reaction mixture was filtered through celite and then evaporated to dryness to give the title compound (0.12 g, 97%) as a clear oil. The reaction flask was purged between H2 (1atm) and vacuum three times After stirring at room temperature for 3 hrs the reaction mixture was filtered through celite evaporated to dryness

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
