Abstract

New syntheses of functionalized pyridines from 3-[amino(methylthio)methylene]-2,4-pentanedionevia its boron chelates were proposed. The products of condensation of dimethylformamide dimethylacetal with the latter chelates were converted into 3-acetyl-2-methylthio-4-hydroxypyridine by refluxing in BuOH and into 1-alkyl-3-cyano-2-methyl-4-pyridones by treatment with primary amines.
