Gold-catalyzed intramolecular hydroarylation of olefins. Scope evaluation and preliminary mechanistic studies
摘要:
We report a gold-catalyzed intramolecular hydroarylation of unactivated olefins using a combination of AuCl(3)/AgOTf as the catalytic system affording dihydrobenzopyrans, tetralins and tetrahydroquinolines in good yields. For our preliminary mechanistic studies, we have investigated the kinetic isotope effects with deuterated arene compounds and found that this catalytic hydroarylation is consistent with an electrophilic aromatic substitution process.

α-Phenylsclenenyl cyclic ethers may be prepared by the reactions of either lactols or lactol acetates with benzeneselenol, or from lactones by the “one-pot” process of reduction and Lewis acid catalyzed selenation. The tetrahydropyranyl phenyl selenides also exhibit a significant anomeric effect and its size has been estimated. The selenenyl ethers are converted to enol ethers through an oxidative elimination
