Diaryliodonium salts are demonstrated as efficient arylating agents of aliphatic alcohols under metal-free conditions. The reaction proceeds at room temperature within 90 min to give alkyl aryl ethers in good to excellent yields. Aryl groups with electron-withdrawing substituents are transferred most efficiently, and unsymmetric iodonium salts give chemoselective arylations. The methodology has...

A facile, efficient, and general synthetic method for a wide range of 2,3-diiodinated 1,4-dihydrothiophenes and naphthalenes has been developed via the electrophilic iodocyclization of various aryl propargyl alcohols. The resulting product 2p can be used for the synthesis of a rubrene intermediate.

A Pd(ii)-catalyzed oxidative alkoxycarbonylation of phenol derivatives with atmospheric pressure of CO-O2 and alcohols has been achieved. The reaction provides an efficient strategy for the synthesis of carboxylic esters and can be applied to the late-stage modification of complex molecules.

The synthesis of highly enantioenriched α-heterocyclic tertiary alcohols has been achieved via lithiation-borylation of a configurationally stable lithiated carbamate and heterocyclic pinacol boronic esters followed by oxidation. Protodeboronation of the α-heterocyclic tertiary boronic esters using TBAF·3H2O or CsF gave highly enantioenriched 1-pyridyl-1-arylethanes in high er.

Abstract Higher alcohols (phenylethyl alcohol and isoamyl alcohol), as the crucial aroma compounds, have been found to associate with sensory properties of various alcoholic products. The Ehrlich Harris pathways are main for yeast produce phenylethyl during brewing process products, whereas specific changes in Wickerhamomyces anomalus under ethanol stress still unclear. In this study, W. NCU003...
