Reaction Steps

A mixture of 240 gm (1 mol) of the diol prepared according to (c) above, 90 gm (1 mol) of acetaldehyde dimethyl acetal, and 0.2 gm of p-toluene sulfonic acid was refluxed for five hours at 70° C. After the reaction was completed, the reaction mixture was taken up in ether, washed neutral with 2 N sodium hydroxide solution, washed with water, and then dried over anhydrous sodium sulfate. The ether and methanol were distilled off, and then the residue was distilled in the oil-pump vacuum. The 14-methyl-13,15-dioxabicyclo[10.5.0]heptadecane obtained was a colorless liquid with the following characteristics:
