Abstract
The combined action of orthoformate and aniline upon cyclohexanedione-1,3 yields anilinomethylene-cyclohexanedione-1,3, which react with cyanoacetate or malodinitrile in DMF in the presence of KOH to give ethyl-1-phenyl-2,5-dioxo-1,2,5,6,7,8-hexahydroquinoline-3-carboxylates (or -carbonitrils)Keywords
