New cardiotonic agents related to amrinone: Synthesis of 1,2-dihydro-5-arylpyridin-2-ones

For development of new cardiotonic agents a serie of 5-aryl-3,4-dihydropyridin-2(1H)-ones, related to amrinone have been prepared from methylquinolines, 2-arylacetic acid or 3-arylethanones by direct aminomethylenation and subsequent condensation-cyclizat

3-Amino-5-(hydroxy- and/or aminophenyl)-6-(lower-alkyl)-2(1H)-pyridinones and cardiotonic use thereof

1-R1 -3-amino-5-(3-R'-4-R"-phenyl)-6-R-2(1H)-pyridinones or salts thereof, which are useful as cardiotonics, where R1 is hydrogen, lower-alkyl, or lower-hydroxyalkyl, R is hydrogen or lower-alkyl, and, R' and R" are each hydrogen, hy
