The norsesquiterpene lactone, platyphyllide has been synthesized in 8 steps in 23% overall yield via the Diels–Alder adduct of 2-(4-methylpent-3-enyl)furan with dimethyl acetylenedicarboxylate, the 3-substituted phthalic diester, and an o-formylbenzamide. An intramolecular ene reaction established the skeleton, and the final step involved inversion of configuration at the benzylic site.
通过 2-(4-甲基戊-3-烯基)呋喃与乙炔二羧酸二甲酯、3-取代邻苯二甲酸二酯和邻甲酰苯甲酰胺的 Diels-Alder 加合物,经过 8 个步骤合成了正链萜内酯--platyphyllide,总收率为 23%。分子内的烯反应建立了骨架,最后一步涉及苄基位点的构型反转。
