摘要

Through our investigation of synthetic routes to tetronic acids, elaboration and cyclization of γ-acetoxy-β-ketoesters were examined. Synthesis of these β-ketoesters 2 has been realized by selective monoacylation of the magnesioenolate of monoethyl malonate. Lactonization of 2 leading to tetronic acids or to 4-alkoxy-furan-2 (5H)-ones is reported.
