Biomimetic syntheses of functionalized γ-resorcylates from 2,2,6-trimethyl-4H-1,3-dioxin-4-one derivatives are reported. Cross metathesis of 2,2-dimethyl-6-vinyl-4H-1,3-dioxin-4-one with homoallylic esters or aldol reactions of tert-butyl or benzyl esters with 1-(2,2-dimethyl-4-oxo-4H-1,3-dioxin-6-yl)-acetone and related ketones followed by aromatization under mild Appel-type reaction conditions gave
报道了从 2,2,6-trimethyl-4H-1,3-dioxin-4-one 衍生物仿生合成功能化 γ-resorcylates。2,2-二甲基-6-乙烯基-4H-1,3-二恶英-4-one 与高烯丙基酯的交叉复分解反应或叔丁基或苄基酯与 1-(2,2-二甲基-4-氧代) 的羟醛反应-4H-1,3-二恶英-6-基)-丙酮和相关酮,然后在温和的 Appel 型反应条件下芳构化,得到一系列 γ-间苯二甲酸酯。
