investigation of the scope of the participation of 2,4,6-(ethoxycarbonyl)-1, 3,5-triazine (1a) and 2.4.6-(methylthio)-1,3,5-triazine (1b) in inverse electron demand Diels-Alder reactions suitable for the preparation of functionalized 5,6-disubstituted pyrimidines is detailed. The use of the resulting [4 + 2] cycloadducts as immediate precursors to the parent 4,5-disubstltuted pyrimldines is described
全面调查2,4,6- (乙氧羰基)-1,3,5-三嗪(1a)和2.4.6- (甲硫基)-1,3,5-三嗪(1b)的参与范围逆电子需求Diels-Alder反应适合于制备官能化的5,6-二取代的嘧啶。描述了将所得的[4 + 2]环加合物用作母体4,5-二取代的嘧啶的直接前体的用途。
