Abstract A new, one-pot, efficient, three-component condensation of benzaldehyde derivatives, enolizable ketones, acetyl chloride, and acetonitrile or benzonitrile in the presence of silica-supported perchloric acid as an effective catalyst for the synthesis of β-amido carbonyl compounds is described. The present methodology offers several advantages, such as good yields, short reaction times, and
摘要 在二氧化硅负载的高氯酸存在下,苯甲醛衍生物、烯醇化酮、乙酰氯和乙腈或苄腈的新型一锅高效三组分缩合反应是合成β-酰胺羰基化合物的有效催化剂。被描述。本方法提供了几个优点,例如良好的收率、较短的反应时间和简单的后处理程序。
