New procedures for the synthesis of 3(2H)-furanones and 4-alkoxy-2(5H)-furanones are reported. Reaction of ketones with the lithium salt of propynal diethyl acetal, followed by treatment of the resulting 4-hydroxy-2-alkynal diethyl acetals with sulfuric a

Acetylenic alcohols, obtained in high yield from condensations of 3,3-diethoxypropyne or 3,3-ethylenedioxybutyne with cyclic ketones, may be used as substrates for cyclopentenone annelation or spirofuranone synthesis.

Ketones are allowed to react with the lithium salt of propynal diethyl acetal and the resulting adducts are treated with sulfuric acid-methanol (1:1) to give the title compounds.
