5-[(3R)-dithiolan-3-yl]pentanamide

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

Procedure: A solution of lipoic acid (25.6 g, 124 mmol), N-hydroxysuccinimide (15.6 g, 136 mmol), and EDC (26.1 g, 136 mmol) in anhydrous CH2Cl2 (300 mL) was stirred overnight at room temperature. The reaction mixture was diluted with ethyl acetate (500 mL) and washed with H2O (500 mL), saturated aqueous NaHCO3 (500 mL), saturated aqueous NaCl (500 mL) and dried (MgSO4). The drying agent was removed by filtration and the filtrate was concentrated to dryness giving the product as a yellow sold (35.4 g, 94%). washed with H2O (500 mL), saturated aqueous NaHCO3 (500 mL), saturated aqueous NaCl (500 mL) dried (MgSO4) The drying agent was removed by filtration the filtrate was concentrated to dryness giving the product as
