| Abstract: | Reactions of Substituted 1-Thiochromones and 4(1H)-Quinolones with Nucleophiles 1-Thiochromone 1a and 4(1H)-quinolone 1b react with nucleophiles to substitute the methylthio group. Compounds of type 1 are suitable C3-fragments for the synthesis of novel heterocycles. Hydroxylamine leads to 2-amino-1-thiochromone-3-carboxamide 7 , whereas 1c gives 2-methylthio-1-thiochromone-oxime 8 . |
