Pyrethroid 중간체 Δ^4-Aldehyde 합성
金寅圭,金永德,金英愛 성균관대학교 기초과학연구소 1985 論文集 Vol.36 No.1
The active ingradients of pyrethrum flowers-pyrethroids-have been showing outstanding insecticidal activity but low mammalian toxicity. Remarkbly, their physiological activity is closely assoiated with cyclopropane ring. A number of synthetic routes to the cyclorproane ring are reported and γ, δ-unsaturated aldehyde plays a key role in many of these synthesis. For this reason, a new versatile synthesis of the aldehyde is reported here. With good yield 5-methyl-4-hexenal was obtained from 2-methyl-3-butene-2-ol and ethyl vinyl ether.
