摘要：
1,3-Dipolar cycloadditon of nitrile oxides, formed in situ by dehydration of primary nitro compounds, with pyrrolidine enamines of protected gamma-hydroxy-beta-keto esters affords isoxazole-4-carboxylates; these are subjected to N-O bond cleavage and lactonisation to afford 3-acyltetronic acids and 3-acyl-4-hydroxytetrahydropyran-2-ones.
