  Reactions of 5-methyl-2H-1, 4-thiazin-3 (4H) -one (4) with various N-acylpyridinium salts (7a-g) led to (N-acyldihydropyridyl) thiazinones (5a-g), oxidation of which yielded a new class of pyridylthiazinones (6a-g). These reactions were applied to the synthesis of other azaarylthiazinones. Some of these azaarylthiazinones, particularly 6- (4-pyridyl) thiazinones (6a, 14a and 14b) showed positive inotropic activity with little chronotropic effect on guinea pig left atria.

  5-甲基-2H-1,4-噻嗪-3(4H)-酮(4)与各种N-酰基吡啶盐(7a-g)反应得到(N-酰基二氢吡啶基)噻嗪酮(5a-g)，将其氧化得到一类新的吡啶基噻嗪酮(6a-g)。这些反应被应用于其他含氮芳基噻嗪酮的合成。其中一些含氮芳基噻嗪酮，特别是6-(4-吡啶基)噻嗪酮(6a, 14a和14b)，显示出了对豚鼠左心房有正性肌力作用和较小的变时效应。
