The reaction of aliphatic ketones with aliphatic or aromatic nitriles in the presence of trifluoromethanesulfonic anhydride has been shown to be a very useful method for the preparation of alkyl- and aryl-pirimidines. The reaction shows a high degree of regioselectivity that depends on the characteristics of the residues attached at the carbonyl group. The results from different branched symmetric
已经表明,在三氟甲磺酸酐存在下,脂族酮与脂族或芳族腈的反应是制备烷基-和芳基-嘧啶的非常有用的方法。该反应显示出高度的区域选择性,这取决于在羰基上连接的残基的特征。显示了来自不同支链对称和不对称酮的结果。分子力学计算可以解释情况并预测得出的结果。描述了烷基芳基嘧啶的区域特异性合成。
