Naphthyridines of formula (I)
, where R is -alkyl, R' is hydrogen or methyl, R" is hydrogen or alkyl, and Q is hydrogen, hydroxy, amino, cyano, carbamyl, carboxy or aminocarbamyl, are useful as cardiotonic agents (1, Q is hydrogen, hydroxy, amino, cyano or carbamyl) and/or intermediates therefor (I, Q is carboxy, aminocarbamyl, hydrogen, amino, cyano or carbamyl). Also shown are pyridinones of formula II
where R and R' are as above and Q' is hydrogen or cyano, which are useful as cardiotonics (II, Q' is hydrogen) and/or intermediates (II, Q' is cyano or hydrogen). Processes for preparing the compounds of Formulas I and II are shown.
式(I)的萘啶类化合物
其中 R 为烷基,R'为氢或甲基,R "为氢或烷基,Q 为氢、羟基、氨基、氰基、氨甲酰、羧基或氨基甲酰,可用作强心剂(1,Q 为氢、羟基、氨基、氰基或氨基甲酰)和/或其中间体(I,Q 为羧基、氨基甲酰、氢、氨基、氰基或氨基甲酰)。图中还显示了式 II 的吡啶酮类化合物
其中 R 和 R'如上,Q'为氢或氰基,可用作强心剂(II,Q'为氢)和/或中间体(II,Q'为氰基或氢)。所示为制备式 I 和 II 化合物的工艺。
