Abstract

Abstract 3, 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. Some 2 ( ...
