Reaction Steps

To the 7-(4-oxo-butyl)-1,4-dioxaspiro[4.5]decane-7-carbaldehyde, 12, obtained in the previous step, was added dibenzylammonium trifluoroacetate (0.4 M solution in THF; 12 mL, 4.8 mmol). The resulting mixture was stirred at room temperature for 3 hours after which the solvent was removed in vacuo. The resulting residue was purified over silica (cyclohexane/EtOAc, 8:2 mixture) to provide 2.3 g (72% yield) of the desired product as a colorless oil which was characterized as follows:
