Phthalimide → HCID 1296952, compound

Participants

Reaction Steps

To a solution of (1R,2S,4S)-bicyclo[2.2.1]heptane-2-ol (1.0 g) in tetrahydrofuran (10 ml) were added phthalimide (1.4 g) and triphenylphosphine (2.6 g), and diethylazodicarboxylate (1.5 ml) dropwise under ice cooling. The mixture was warmed to ambient temperature and stirred for 24 hours. The reaction solution was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (n-hexane:ethyl acetate)=100:0 to 95:5) to obtain 2-[(1R,2R,4S)-bicyclo[2.2.1]hept-2-yl]-1H-isoindole-1,3(2H)-dione (1.4 g) as a colorless solid.
