Mucochloric Acid: A Useful Synthon for the Selective Synthesis of 4-Aryl-3-chloro-2(5H)-furanones, (Z)-4-Aryl-5-[1-(aryl)methylidene]-3-chloro-2(5H)-furanones and 3,4-Diaryl-2(5H)-furanones

4-Dichloro-2(5H)-furanone, which has been prepared efficiently from mucochloric acid, has been transformed selectively into 4-aryl-3-chloro-2(5H)-furanones either by Suzuki- or Stille-type reactions. These monochloro derivatives have been used as precursors either to (Z)-4-aryl-5-[1-(aryl)methylidene]-3-chloro-2(5H)-furanones, including naturally occurring rubrolide M, or to unsymmetrical 3,4-diaryl-2(5H)-furanones
由粘氯酸有效制备的3,4-二氯-2(5 H)-呋喃酮已通过Suzuki-或Stille-选择性地转化为4-芳基-3-氯-2(5 H)-呋喃酮类型反应。这些一氯衍生物已被用作(Z)-4-芳基-5- [1-(芳基)亚甲基] -3-氯-2(5 H)-呋喃酮的前体,包括天然存在的罗布洛尔M,或不对称的前体。 3,4-二芳基-2(5 H)-呋喃酮。约2(5 H已经发现,如此制备的呋喃酮衍生物在体外对NCI三细胞系面板表现出显着的细胞毒性活性,但是对NCI人肿瘤60细胞系面板的细胞毒性有限。(©Wiley-VCH Verlag GmbH&Co.KGaA,69451 Weinheim,Germany,2003)
