1-(3,3-Diethoxypropyl)-1-[(dihexylphosphoryl)methyl]-3-phenylurea in the Synthesis of 4-Aryl-Substituted Tetrahydropyrimidin-2-ones

摘要

First specimens of 4-aryl-substituted tetrahydropyrimidin-2(1H)-ones containing a phosphoryl group were obtained through the reaction of 1-(3,3-diethoxypropyl)-1-[(dihexylphosphoryl)methyl]-3-phenylurea with resorcinol and its derivatives in the presence of trifluoroacetic acid.
