mild and efficient Fe(ClO4)3·×H2O-catalyzed direct C–C bond coupling reactions of 1,3-dicarbonyl compounds, electron-rich arenes and heteroarenes and 4-hydroxycoumarin with secondary benzylic alcohols have been described. The benzylation of electron-rich arenes and heteroarenes leads to the synthesis of bis-symmetrical triarylmethanes. The present method is also applied to synthesis of an anti-coagulant
已经描述了温和有效的Fe(ClO 4)3 ·×H 2 O催化的1,3-二羰基化合物,富电子芳烃和杂芳烃以及4-羟基香豆素与仲苄醇的直接C-C键偶联反应。富电子芳烃和杂芳烃的苄基化导致双对称三芳基甲烷的合成。本发明的方法也适用于合成一个的抗-coagulant化合物,4-羟基-3-(1,2,3,4-四氢萘-1-基)-2- ħ从市场上可买到的底物中得到-铬-2--2-酮(香豆基(B)),产率为85%。该协议的优点是范围广,条件温和,使用廉价的催化剂以及操作简便,因为水是唯一的副产品。
