A convenient approach to the synthesis of 6-substituted 1,5-dialkyluracils and -2-thiouracils
摘要:
A general and convenient approach to the synthesis of 6-substituted 1,5-dialkyluracils and 2-thiouracils via 1,5-dialkyl-6-(methylsulfonyl) uracils 1 and 1,5-dialkyl-6-(methylsulfinyl)-2-thiouracils 2, respectively, has been described. The compounds 1 and 2 were synthesized from ethyl 2-alkyl-3,3-di(methylthio)acrylates 3 in live steps in good yields.
