Potassium Carbonate → HCID 58399414, compound

Participants

Reaction Steps

To a solution of 8-(benzyloxymethyl)-1,4-dioxaspiro[4.5]decane-8-carbaldehyde (Reference Example 86) (100 mg, 0.344 mmol) in methanol (5.2 mL), potassium carbonate (143 mg, 1.03 mmol) and dimethyl-1-diazo-2-oxopropylphosphonate (165 mg, 0.861 mmol) were added with stirring under ice-cooling, and the obtained solution was stirred at room temperature for 1 hour. The reaction was quenched by adding water to the reaction solution, and the resulting solution was extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was purified by flash chromatography (silica gel, n-hexane/ethyl acetate) to obtain the captioned compound (88.9 mg, 0.310 mmol, 90%) as a colorless oily compound.
