実験手順
The above vinyl ether was dissolved in benzene (100 ml.) and the solution was refluxed for 120 hours under Argon. The solvent was removed at reduced pressure to give a yellow oil (~ 1.289 g.). This was chromatographed on 25 g. of silica gel and elution with 1:9 parts by volume of ether:petroleum ether (b.p. 30°-60°) gave 792 mg. of material. This was further purified by Kugelrohr distillation at 36°/0.5 mmHg to yield 3(S),7-dimethyl-4trans)octenal as a colorless oil, [α] D25 + 30.18° (c= 3.572, CHCl3).
