- Synthesis of chlorinated 5-hydroxy 4-methyl-2(5H)-furanones and mucochloric acid
-
An improved procedure for the synthesis of chlorinated 5-hydroxy-4-methyl-2(5H)-furanones is described. By this method also carbon-labelled (13C and 14C at C-3) hydroxyfuranones, including mucochloric acid, can be prepared. Each step of the method was examined in an effort to optimize both the yield and the purity of the compounds.
