Abstract

The successful synthesis of novel tetrahydropyrimido[4,5-b][1,6]naphthyridine derivatives is reported. 1-Benzyl-3,5-bis[(E)-arylmethylidene]tetrahydropyridin-4(1H)-ones prepared via Knoevenagel condensation of 1-benzyl-4-piperidinone with aromatic aldehydes undergo condensation with 6-aminouracils in acetic acid to afford the desired products. Structures of the products are confirmed by analytical data and X-ray crystallography analysis.
