Active malonic esters condense with 2-pyridylacetonitrile giving 1-cyano-3-substituted 2-hydroxyquinolizin-4-ones. Catalytic hydrogenation of the resulting products led to the corresponding 1-cyano-3-substituted-2-hydroxy-6.7.8.9-tetrahydroquinolizin-4-ones. On the other hand, condensation of the active malonic esters with beta-aminocrotononitrile afforded 5-cyano-3-substituted-4-hydroxy-6-methylpyridine-2-ones. The IR and NMR data are reported.
活性丙二酸酯与2-吡啶基乙腈缩合生成1-氰基-3-取代的2-羟基喹嗪-4-酮。所得产物的催化氢化反应生成相应的1-氰基-3-取代-2-羟基-6,7,8,9-四氢喹嗪-4-酮。另一方面,活性丙二酸酯与β-氨基巴豆腈缩合得到5-氰基-3-取代-4-羟基-6-甲基吡啶-2-酮。报道了红外光谱和核磁共振数据。
