Participants

Reaction Steps

A solution of diethyl azodicarboxylate (2.58 mL, 16.4 mmol) in anhydrous THF (10.0 mL) was added dropwise to a mixture of (1R,2R,4R,5S)-5-(tert-butyldiphenylsilyloxy)bicyclo[2.2.1 ]heptan-2-ol (5.00 g, 13.6 mmol), phthalimide (2.31 g, 15.7 mmol), and triphenyl phosphine (4.11 g, 15.7 mmol) in anhydrous THF (60 mL) at ambient temp. under nitrogen. After stirring for 32 h, the solvents were removed in vacuo. The residue was purified by flash column chromatography (0 to 20% of ethyl acetate in hexanes) to give the title compound as a white solid. MS m/z: 496.3 (M+H)+.
