  摘要：

  Condensation of cyanothioacetamide with sodium salts of 2-(Hydroxymethylene)-1-cycloalkanones afforded the corresponding pyridine-2(1H)-thiones 4. Compounds 4 served as a key intermediates for the synthesis of condensed 2,4-diaminopyrido[2,3-d]pyridines 7. Compounds 7 were of interest as potential inhibitors of dihydrofolate reductase.

  The action of Raney nickel on substituted 3-cyano-2-methylthiopyridines was studied. Under conditions of catalytic hydrogenation, the reaction yields a mixture containing the aminosulfide resulting from reduction of the nitrile group with retention of the methylthio group, the nitrile resulting from elimination of the methylthio group, and the amine resulting from both reduction of the nitrile group

  研究了雷尼镍对取代的 3-氰基-2-甲基硫代吡啶的作用。在催化加氢条件下，反应生成的混合物含有由腈基还原而保留甲硫基的氨基硫化物、由甲硫基消除的腈和由腈基和甲硫基同时还原产生的胺。消除甲硫基。在脱硫条件下用大量阮内镍处理 3-氰基-2-甲硫基吡啶可同时消除甲硫基和将腈基还原为氨基甲基。在甲醇或四氢呋喃中还原脱硫生成伯胺，而在异丙醇或乙醇中反应生成仲胺或叔胺，
