Participants

Reaction Steps

To a stirred solution of 4-Allyl-3-hydroxy-piperidine-1-carboxylic acid benzyl ester (293 mg, 1.06 mmol) were added triphenyl phosphine(362 mg, 1.38 mmol), a solution of diethyl azodicarboxylate in toluene (0.6 ml, 1.38 immol; 40% solution) and DPPA (297 μL, 1.38 mmol). After stirring for 4 h, the mixture was evaporated and the residue was purified by column chromatography (15% AcOEt-hexane)to give 4-Allyl-3-azido-piperidine-1-carboxylic acid benzyl ester.
