An efficient synthesis of 3-cyanoquinoline derivatives
摘要:
A short aid efficient method is reported for the preparation of 3-cyanoquinoline derivatives. Reaction of 3,3-dimethoxy-2-formyl-propanenitrile sodium salt 1 with various anilines 2 afforded (E) enamines 3 which were subsequently isomerized into (Z) enamines 4 and cyclized in a one pot procedure to give 3-cyanoquinolines 5 in good yields.
