showed characteristic reactivities towards nucleophiles, yielding ureas (II), carbamates (IV), and dimethoxy-derivatives (VI), when treated with methoxide ion. These reactions are affected by the nature and position of the substituents in the dihydropyrimidines.
5,6-二氢尿嘧啶及其甲基衍生物(I)的硫代类似物显示出对亲核试剂的特征性反应性,用甲醇根离子处理后可产生脲(II),氨基甲酸酯(IV)和二甲氧基衍生物(VI)。这些反应受二氢嘧啶中取代基的性质和位置的影响。
