Abstract:Thymine was synthesized in 64.5% yield from ethyl propionate,ethyl formate,thiourea and hydrogen peroxide in four reaction steps including condenstation,cyclization,oxidation and neutralization. The structure of the target compound was identified by IR. The raw materials in the synthetic rout were easily available. The technology is easy to operate and be industrialized. |
Key words:thymine;thiourea;synthesis |
