Several amide oximes underwent condensation reactions with dimethyl acetylene dicarboxylate to afford 1:1 adducts. Under basic conditions, these adducts underwent ring closure to afford several methyl [3-(substituted)-4,5-dihydro-5-oxo-6H-1,2,4-oxadiazin-6-ylidene]acetates. The reactions of these compounds with a variety of amines resulted in addition-rearrangement reactions with the formation of the
几种酰胺肟与乙炔二甲酸二甲酯进行缩合反应,得到1:1的加合物。在碱性条件下,对这些加合物进行闭环反应,得到几种[3-(取代)-4,5-二氢-5-氧代-6 H -1,2,4-氧二嗪-6-亚烷基]乙酸甲酯。这些化合物与多种胺的反应导致加成-重排反应,形成相应的甲基2-取代的5-取代的氨基-1,6-二氢-6-氧代-4-嘧啶羧酸酯。
