Abstract

A tioféngyűrűs fungicidek 3-karbometoxi-4,5-dimetil-tiofén előanyagbólkészíthetők el. Ez a vegyület és a vele rokon vegyületek előállíthatókegy a-merkaptoketonnak, például a 3-merkapto-2-butanonnak egyakriláttal, például metil-3-metoxi-akriláttal alkoxid bázis, példáulnátrium-metoxid (NaOMe) jelenlétében történő reagáltatásával, melyeredményeként egy helyettesített tetrahidrotiofént nyernek, amit savaskezeléssel aromás tiofénné alakítanak. A helyettesítetttetrahidrotiofén új vegyület. Ó
