Abstract
Si descrive un procedimento per la preparazione di diidropiridine, mediante condensazione di Knoevenagel tra una benzaldeide e un estere acetoacetico in presenza di ?-alanina come catalizzatore, e successiva ciclocondensazione tra il risultante estere benziliden acetoacetico e un estere ammino crotonico.
