A series of N-substituted 3,5-bis(substituted-idene)piperidin-4-ones have been prepared using solidphase organic synthesis. The synthesis starts with a Michael addition with piperidin-4-one serving as the donor and REM resin as the acceptor. Various aldehydes were then utilized through a Knoevenagel

β¦ Synopsis
An efficient solid-phase synthetic approach for the synthesis of N-substituted 3, 4-dihydroquinazolinone derivatives has been developed. Four different 2-nitrobenzoic acids and three different 2-phenylacetyl chlorides were employed in the synthesis of this library. After purification, all products were obtained in good yields.
