Abstract

An additive-free and diastereoselective [4 + 1] annulation between ortho-hydroxyphenyl-substituted para-quinone methides and CF3-substituted imidoyl sulfoxonium ylides is developed, providing a facile and practical route to diverse trans-2,3-dihydrobenzofurans with high efficiency. This protocol features mild conditions, broad substrate scope and easy to operate.

通过 p-QMs 和 TFISYs 之间的 [4 + 1] 嵌合实现反式二取代-2,3-二氢苯并呋喃的无加成和非对映选择性合成

本研究开发了一种无添加剂和非对映选择性的[4 + 1]环化反应，该反应介于正羟基苯基取代的对苯醌甲酯和 CF3 取代的咪唑酰亚磺酰亚胺之间，为高效制备多种反式-2,3-二氢苯并呋喃提供了一条简便实用的途径。该方案具有条件温和、底物范围广、操作简便等特点。
