Coupling of terminal alkynes with protected 5-iodouracil nucleosides in the presence of dichlorobis(triphenylphosphine)palladium and copper(I) iodide in triethylamine gives the corresponding 5-(alkyn-1-yl)uracil nucleosides in 72–92% yields.
在三乙胺中存在二氯双(三苯基膦)钯和碘化铜(I)的情况下,末端炔烃与受保护的5-碘尿嘧啶核苷的偶联以72-92%的收率得到相应的5-(炔-1-基)尿嘧啶核苷。
