Synthesis of some new 1,3-diaryl-5-(2,3-dihydrobenzoxazol-2-ylidene)-2-thiobarbituric acids

Abstract

1129-11311,3-Diaryl-5-(2, 3-dihydrobenzoxazol-2-ylidene)-2-thiobarbituric acids 3 have been synthesized by the condensation of o<span style="mso-bidi-font-style: italic">-aminophenol with the corresponding 5-bis(methylmercapto)methylene 2 and <b style="mso-bidi-font-weight: normal">5-ethoxy methylene derivative 4 of 1,3-diaryl-2- thiobarbituric acids <b style="mso-bidi-font-weight: normal">1. The structure of the synthesized compounds have been established on the basis of their elemental analysis and spectral data.</span
