Halocyclization of 2-allyl(propargyl)sulfanyl-6-aminopyrimidin-4(3H)-ones
摘要:
The alkylation of 6-amino-2-thiouracil with allyl, methallyl, and propargyl halides in the presence of bases gave 2-[allyl(methallyl, propargyl) sulfanyl]-6-aminopyrimidin-4(3H)-ones which reacted with iodine and bromine to form fused [1,3] thiazolo[3,2-a] pyrimidinium systems. Their nitrosation with sodium nitrite in acid medium afforded 2-[allyl(propargyl) sulfanyl]-6-amino-5-nitrosopyrimidin-4(3H)-ones.
