Benzyl chloroformate → HCID 67490951, compound

Participants

Reaction Steps

Benzyl chloroformate (1.72 mL, 12.0 mmol) was added to a solution of 7-benzyl-1-(3-buten-1-yl)-3-oxa-7-azabicyclo[3.3.0]octan-2-one (1.09 g, 4.02 mmol) in dichloromethane (13.4 mL) in a nitrogen atmosphere, and the mixture was stirred at room temperature for five days. The reaction solution was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=100:0→90:10→84:16→80:20→75:25→66:34→50:50) to give 1.13 g of the title compound.
