Synthesis of ethyl 3-amino-5-arylthiophene-2-carboxylates based on α-chlorocinnamonitriles
摘要:
A new procedure was developed for preparation of ethyl 3-amino-5-arylthiophene-2-carboxylates by the reaction of alpha-chlorocinnamonitriles and their analogs with ethyl mercaptoacetate for a wide range of substrates. The reaction products form in high yields.
