Abstract
Electrophilic condensation of pyrimidines with cyclic ketones was investigated. As nucleophiles, the degree of ionization of pyrimidines in acidic media and the electron density on the C-5 determined the reactivity. An electron-rich nitrogen at the 4-position of cyclic ketones facilitated the reaction. This method is facile for the synthesis of 5-vinyl substituted pyrimidines as k(cat) antifolates.
