摘要：

Cycloaddition of diethylphosphonomethyl nitrile oxide to the enamine from ethyl acetoacetate produces 4-ethoxycarbonyl-3-diethoxyphosphonylmethyl-5-methylisoxazole; condensation of the phosphonate with aldehydes and ketones gives 3-alkenylisoxazoles that are cleaved by hexacarbonylmolybdenum to afford unsaturated alpha-alkoxycarbonyl-beta-diketones.
