Quiroga, Jairo et al. published their research in Tetrahedron Letters in 2006 | CAS: 54030-56-7

6-Amino-3-methyl-2-(methylthio)pyrimidin-4(3H)-one (cas: 54030-56-7) belongs to pyrimidine derivatives. Pyrimidine is an aromatic heterocyclic organic compound similar to pyridine. Pyrimidine derivatives also play an important role in drug development, either in concert with other compounds or on their own.Electric Literature of C6H9N3OS

Three-component synthesis of hexahydropyridopyrimidine-spirocyclohexanetriones induced by microwave was written by Quiroga, Jairo;Cruz, Silvia;Insuasty, Braulio;Abonia, Rodrigo;Nogueras, Manuel;Cobo, Justo. And the article was included in Tetrahedron Letters in 2006.Electric Literature of C6H9N3OS This article mentions the following:

Spiro pyridopyrimidinone cyclohexanediones and pyrimido[4,5-b]quinolinones were obtained in a three-component microwave-assisted reaction of 6-aminopyrimidin-4-ones with dimedone and formaldehyde solution or paraformaldehyde, resp. A mechanism is proposed based on the presence of a basic catalyst (Et3N in this case) and the fact that single condensation intermediates are isolated prior to the cyclization leading to the final products. In the experiment, the researchers used many compounds, for example, 6-Amino-3-methyl-2-(methylthio)pyrimidin-4(3H)-one (cas: 54030-56-7Electric Literature of C6H9N3OS).
