  A general route to 1,2,4-trisubstituted pyrimidines is described in one to three steps from a common key precursor, diazadienium iodide 2. An efficient preliminary [4+2] cyclocondensation reaction between the azabutadiene building block 2 and various iso(thio)cyanates constitutes an original construction of the pyrimidine skeleton. Subsequent structural modifications on the heterocycle allow the elaboration

  日期：——

  A facile and simple regioselective synthesis of uracils and their thio analogues has been achieved by cyclocondensation of a common precursor, diazadienium iodide 1, and isothiocyanates 2a,b. The key step in this synthetic process is the preparation of 4-methylsulfanylpyrimidine-2-thiones 3a,b, which after further elaboration gave the expected uracil analogues 4a,b-8a,b.

  通过共同前体碘化二氮杂二烯鎓 1 和异硫氰酸酯 2a、b 的环缩合反应，实现了尿嘧啶及其硫代类似物的简便和区域选择性合成。该合成过程中的关键步骤是制备 4-甲基硫基嘧啶-2-硫酮 3a,b，经过进一步加工得到预期的尿嘧啶类似物 4a,b-8a,b。
