摘要: Abstract The title compounds have usually been prepared as their sodium salts by Claisen condensations with acetic and oxalic acid esters strong bases such alkoxides catalysts.1,2 In this communication we want to present a very mild convenient route both starting from the corresponding methyl or ethyl acetylenedicarboxylates.
