1. eq.), and potassium phosphate tribasic (0.0121 g, 0.057 mmol, 1.5 eq). The vial was vacuum evacuated and refilled with N 2 gas three times. Anhydrous DMF (1.0 mL) was added, and the solution was degassed by applying a vacuum to the vial and swirling, followed by N 2 flush. After two degassing cycles the vial was stirred under N 2 at 80 �C for 12 h. After, the reaction was allowed to cool to rt and diluted with EtOAc (15 mL), washed with water (1 x 15 mL) and brine (1 x 15 mL), dried with Na 2 SO 4 , filtered, and the solvent was removed under reduced pressure;Di-O-Isopropylidene-1,6-Anhydro-D-Glycero-Dgalactitol;Into a 20 mL vial containing 2-O,2000
