A One-Step Fusion of 1,3-Thiazine and Pyrimidine Cycles
摘要:
The chlorotrimethylsilane-promoted Biginelli type reactions of aldehydes, thiourea, and cyanoketones led to a diverse set of tetrahydropyrimidine2(1H)-thiones. Under similar conditions, thioureas, benzaldehyde, and cyanoacetamide reacted to give first representatives of hexahydro-5H- pyrimido[5,4-e][1,3]thiazin-5-ones in high preparative yield.
