Previously unknown vinylogs of 2(3)-aminomethylene-substituted benzothiophene-3-one, 1-methyloxindole, 1-methylindoxyl, benzofuran-3-one, and indan-1,3-dione have been synthesized.Their tautomeric transformations have been studied by methods of UV, IR, and PMR spectroscopy.It has been shown that the introduction of a substituent into the β position of a dienic chain favors the appearance of the cyclic form.
