Reaction Steps
To a stirring solution of 4.05 g (28 mmol) of methyl 4-oxohexanoate (16), prepared as described above in Example 16, in 200 mL of toluene and 0.53 g (2.8 mmol) of tosyl acid was added 5.59 g (90 mmol) of ethylene glycol. After refluxing for 2 hours using a Dean-Stark trap, the solvent was removed under vacuum. The resulting orange oil was dissolved in 200 mL of EtoAc. The EtoAc was then washed with 2×200 mL of H2O. The organic layer was then dried over Na2SO4 anhydrous, filtered, and concentrated in vacuo to yield 4.96 g (94%) of methyl 2-ethyl-1,3-dioxolane-2-propanoate (17), which was employed immediately in Example 18 below.
