The intramolecular hydroarylation of alkynes using a substoichiometric amount of FeCl3 is described. When starting from tetrasubstituted substrates, products resulting from an unexpected toluene (or xylene) elimination are isolated in good yields.

Here, we describe highly efficientintramolecularhydroarylations mediated by Re2O7/HReO4. Styrene derivatives of different electronic properties have been activated to effect a challenging intramolecularhydroarylation for the facile access to various substituted 1-aryltetralin structures. This method is characterized by mild reaction conditions, broad substrate scope, high chemical yields, and 100%
在这里,我们描述了由 Re 2 O 7 /HReO 4介导的高效分子内加氢芳基化。不同电子特性的苯乙烯衍生物已被激活,以实现具有挑战性的分子内加氢芳基化,从而轻松获得各种取代的 1-芳基四氢化萘结构。该方法具有反应条件温和、底物范围广、化学收率高、原子经济性100%等特点。iso CA-4 类似物的有效全合成例证了该方法的潜在合成应用。
