    Reactions of 5-acetyl-1-aryl(alkyl)-6-methyl-4-methylsulfanylpyrimidine-2(1H)-thiones (prepared from diacetylketene N,S-acetal) with guanidine afforded 3-alkyl- and 3-aryl-7-amino-5-methyl-4-methylidene-3,4-dihydropyrimido[4,5-d]pyrimidine-2(1H)-thiones. By-products of these reactions (5-acetyl-1-alkyl(aryl)-6-methyl-2-thiouracils) can also be obtained from the starting pyrimidinethiones and EtONa in EtOH. Pyrimidopyrimidinethiones can react with MeOH at the methylidene group in the presence of MeONa.

    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.
