A new synthesis of 3-carboxy-2,5-disubstituted furans and their conversion to 5-vinyl derivatives

A new route to the title compounds is described. The key transformation involves treatment of a 2-(4-keto-2-alkynyl)-3-ketobutanoate with silica gel or Et3N to effect ring closure and subsequent double bond isomerization. (C) 2000 Elsevier Scie
