Participants

Reaction Steps

To a 100 mL flask was added 1-benzyl 2-methyl aziridine-1,2-dicarboxylate (1 g, 4.25 mmol), dichloromethane (12 mL), (R)-1-Chloro-2-propanol (0.76 mL, 8.50 mmol), and boron trifluoride diethyl etherate (0.05 mL, 0.398 mmol). The mixture was stirred at room temperature for 15 minutes Solvent was removed in vacuo and the residue purified on silica gel eluting with Hexanes-EtOAc (0-50%) to give (R)-methyl 2-(benzyloxycarbonylamino)-3-(1-chloropropan-2-yloxy)propanoate (583 mg, 41%). MS [M+H] found 330.2.
