has been accomplished by employing aryl boric acid/Fe(OTf)3. Significant progress was obtained in utilizing an extremely broad substrate scope, giving indanones in high yields with high regioselectivities and diastereoselectivities. The mechanistic investigation supports a bidentate diiron Lewis acid catalysis, and the strong double electrophilic activation of aryl vinyl ketones via simultaneous coordination
通过使用芳基硼酸/ Fe(OTf)3可以完成未活化的芳基乙烯基酮的高效催化Nazarov反应。在利用极其广泛的底物范围方面获得了重大进展,从而以高产率获得了茚满酮,并具有较高的区域选择性和非对映选择性。机理研究支持双齿二铁路易斯酸的催化,芳基乙烯基酮通过同时配位的强双亲电活化在实现高反应效率方面起着关键作用。
