A one-pot three-component synthesis of dihydropyrimidinones via a molecular iodine-catalyzed tandem reaction of simple readily available mono-substituted urea, alkylaldehyde, and arylaldehyde has been developed. The reaction proceeds with high chemo- and regioselectivity to give highly diverse dihydropyrimidinones in reasonable yields under mild reaction conditions. Moreover, the first catalytic enantioselective
通过分子碘催化的简单易得的单取代脲、烷基醛和芳醛的串联反应,已开发出一锅三组分合成二氢嘧啶酮。该反应以高化学和区域选择性进行,在温和的反应条件下以合理的产率得到高度多样化的二氢嘧啶酮。此外,该反应的第一个催化对映选择性版本也是通过使用手性螺环 SPINOL-磷酸实现的。
