A cross‐coupling reaction of cyanopyrimidines with aliphatic alcohols, thiols (or S‐alkylisothiourea salts) or amines gives the corresponding alkoxylpyrimidines, aminopyrimidines or alkylthiopyrimidines. The wide substrate scope with excellent yields makes cyanopyrimidines a promising alternative substrate class to the frequently used pyrimidines halides for the formation of C–O, C–S, and C–N bonds
氰基嘧啶与脂族醇,硫醇(或S-烷基异硫脲盐)或胺的交叉偶联反应可得到相应的烷氧基嘧啶,氨基嘧啶或烷基硫嘧啶。宽范围的底物范围和优异的收率使氰基嘧啶成为用于形成C–O,C–S和C–N键的常用嘧啶卤化物的有前途的替代底物类别。
