Procedure
5-(6-Azidohexanoyl)-2,2-dimethyl-1,3-dioxane-4,6-dione was heated with 3-hydroxypropionitrile (8.90 g, 125 mmol) at 80° C. until no more CO2 was released. The reaction mixture was diluted with 150 ml of 2-propanol and 4-nitrobenzaldehyde (6.30 g, 41.7 mmol), piperidine (178 mg, 2.10 mmol) and acetic acid (125 mg, 2.10 mmol) were added. The mixture was stirred at room temperature for 48 hrs. After the solvent was evaporated, the residue was dissolved into CHCl3 (200 ml), washed with water (150 ml) and brine (150 ml). After drying (Na2SO4) and evaporation of solvent, 8-azido-2-[ (4-nitrophenyl)methylene]-3-oxooctanoic acid 2-cyanoethyl ester was obtained as a brownish oil (17.0 g, 100%).
