Reaction Steps

Using the procedure of Example 51, propionaldehyde and 2-ethyl-2-(2-fluorobenzyloxy)-1,3-propanediol were reacted, using hexane as solvent, to give, after separation by column chromatography, r-2-ethyl-5-ethyl-t-5-(2-fluorobenzyloxy)-1,3-dioxane, b.p. 89°-90°/0.01 mm, nD26 1.4895; and r-2-ethyl-5-ethyl-c-51 -(2-fluorobenzyloxy)-1,3-dioxane, b.p. 93°-95°/0.01 mm, nD26 1.4902. The ir and nmr spectra were consistent with the assigned structures.
