The reaction of 2-chloro-N-(3-oxoalkenyl)acetamides with 1,3-benzothiazole-2(3H)-thione, 1,3-benzoxazole-2(3H)-thione, and 1-methyl-1,3-dihydro-2H-benzimidazole-2-thione led to the formation of 2-(heteroarylsulfanyl)-N-(3-oxoalkenyl)acetamides. By the action of a base, these compounds were converted into pyridin-2(1H)-ones containing a divalent sulfur atom in position C-3 bonded to a heterocyclic ring. Bromination, nitration, alkylation of 3-(1,3-benzothiazol-2-ylsulfanyl)pyridin-2(1H)-ones have been studied. The action of zinc in acetic acid transformed these compounds into 3-sulfanylpyridin-2(1H)-ones.

2-氯-N-（3-氧代烯基）乙酰胺与1,3-苯并噻唑-2（3 H）-硫酮，1,3-苯并恶唑-2（3 H）-硫酮和1-甲基-1的反应，3-二氢-2 H-苯并咪唑-2-硫酮导致形成2-（杂芳基硫烷基）-N-（3-氧代烯基）乙酰胺。在碱的作用下，这些化合物被转化为在与杂环键合的C-3位上含有二价硫原子的吡啶-2（1 H）-1 。已经研究了3-（1,3-苯并噻唑-2-基硫烷基）吡啶-2（1 H）-一的溴化，硝化和烷基化。锌在乙酸中的作用将这些化合物转化为3-硫烷基吡啶2-2（1 H）-one。
