A highly regioselective and diastereoselective oxa-Diels-Alder reaction catalyzed by AlCl3 has been developed. This reaction is efficient and characterized by good functional group compatibility, F, Cl, CN, NO2, OMe and thiophenyl groups are tolerated. A Lewis acid catalyzed concerted cycloaddition mechanism is proposed based on the results.
已经开发了由AlCl 3催化的高度区域选择性和非对映选择性的oxa-Diels-Alder反应。该反应是有效的并且以良好的官能团相容性为特征,可以容忍F,Cl,CN,NO 2,OMe和硫代苯基。基于该结果,提出了路易斯酸催化的协同环加成机理。
