Reaction Steps

To a homogeneous solution of 5,5-dimethyl-3-(3-nitropyridin-4-yl)cyclohex-2-enol (1.0 eq), triphenyl phosphine (1.5 eq), and phthalimide (1.5 eq) in THF (0.2 M) cooled to 0° C., ditertbutyl azodicarboxylate (1.5 eq) in THF was added to the solution. The mixture was stirred at 0° C. for 2 hours. The reaction was concentrated in vacco. The residue was purified by column (5% methanol in 1:1 ethyl acetate and hexanes) to give 2-(5,5-dimethyl-3-(3-nitropyridin-4-yl)cyclohex-2-enyl)isoindoline-1,3-dione (99%). LC/MS (m/z): MH+=378.2, Rt=1.10 min.
