Synthesis of 2-Alkylamino/Alkoxy-3-Arylthieno[3,2-d]Pyrimidin-4(3<i>H</i>)-One Derivatives

Abstract

The title compounds 2-alkylamino/alkoxy-3-arylthieno [3,2-pyrimidin-4(3H)-ones were synthesized by base catalytic reactions of primary amines or alcohols with carbodiimides,which were obtained from the aza-wittig reaction of iminophosphorane 2 and arylisocyanates.The conditions of cyclization and spectral properties were researched.
