実験手順

After the reaction, MeOH was recovered, following by the same treatment as above to give 9.47 g. of crude 6,6-dimethoxycaproic acid methyl ester. Then, a 10 wt.% aqueous hydrochloric acid solution was added to this crude product, followed by stirring for 6 hours at room temperature. The reaction mixture was treated by usual method to give crude products. Pure 3.20 g. of 5-carbomethoxy-1-pentanal was obtained by column chromatography.
