Abstract

The solid phase synthesis of 1, 3, 5-trisubsituted pyridin-2-ones is reported via selective 1NH-alkylation of 3-amino-5-carbomethoxy-1H-pyridin-2-one with a solid-supported halo- acid. Coupling of an acid to solid-supported 3-aminopyridinone was followed by saponification of the methyl ester to give the acid. Activation of the acid via the pentafluorophenyl ester allowed reaction with an amine, and cleavage from the solid ...
