Two families of bicyclic fluorinated uracils have been prepared starting from a gem-difluorinated unsaturated nitrile, by means of a ring-closing metathesis reaction to form the new ring, which is fused at the C-5/C-6 or N-1/C-6 positions of the uracil moiety. The selective formation of olefin regioisomers in the metathesis process can be controlled according to the reaction conditions (catalyst, solvent
已通过闭环易位反应形成了新的环,并从C-5 / C-6或N-1 /处稠合,从宝石-二氟不饱和腈开始制备了两个家族的双环氟化尿嘧啶。尿嘧啶部分的C-6位。复分解过程中烯烃区域异构体的选择性形成可以根据反应条件(催化剂,溶剂和温度)进行控制。还研究了所得化合物的杀螨活性。
