SYNTHESIS OF 3-METHYL-4-CYANO-3-BUTENOIC ACID AMIDES AND THEIR CYCLIZATION INTO 6-AMINO-2-PYRIDONES

Article abstract of DOI:10.1007/BF00531293

Two groups of amides, derivatives of 3-methyl-4-cyano- and 3-methyl-4-cyano-4-carbethoxy-3 acids were obtained from acetoacetamides in the form of mixtures of Z,E-isomers and the pure E-isomers were isolated.It was shown that amides from the first group a
