A highly efficient and general method for the synthesis of 5-(2-acylethynyl)-2,4-dimethoxypyrimidines starting from 2,4-dimethoxy-5-/2-(trimethylsilyl)ethynyl/pyrimidine is described. The 5-(2-acylethynyl)-2,4-dimechoxypyrimidines have been converted to 5-(2-acyl-1-iodovinyl) uracils and 5-(2-acylethynyl) uracils.
描述了从2,4-二甲氧基-5- / 2-(三甲基甲硅烷基)乙炔基/嘧啶开始合成5-(2-酰基乙炔基)-2,4-二甲氧基嘧啶的高效且通用的方法。5-(2-酰基乙炔基)-2,4-二苯氧基嘧啶已被转化为5-(2-酰基-1-碘乙烯基)尿嘧啶和5-(2-酰基乙炔基)尿嘧啶。
