Abstract Microwave irradiation of mixtures of 4-arylmethylene-2-phenyloxazol-5(4H)-ones and enaminocarbonyl compounds, in the absence of solvent, affords dihydropyridinone derivatives in quantitative yields. From 4-ethoxymethylene-2-phenyloxazol-5(4H)one and enaminocarbonyl compounds, pyridinone derivatives are obtained.
摘要 4-芳基亚甲基-2-苯基恶唑-5(4H)-酮和烯氨基羰基化合物的混合物在没有溶剂的情况下进行微波照射,以定量产率提供二氢吡啶酮衍生物。从4-乙氧基亚甲基-2-苯基恶唑-5(4H)酮和烯氨基羰基化合物得到吡啶酮衍生物。
