Gold-catalyzed three-component coupling: oxidative oxyarylation of alkenes.
The three-component coupling of terminal alkenes with arylboronic acids and oxygen nucleophiles is described. The reaction employs a binuclear gold(I) bromide as a catalyst and Selectfluor reagent as the stoichiometric oxidant. Alcohols, carboxylic acids, and water can be employed as oxygen nucleophiles, thus providing an efficient entry into beta-aryl ethers, esters, and alcohols from alkenes.
متن کاملRh-Catalyzed Intermolecular Syn-Carboamination of Alkenes via a Transient Directing Group
Alkenes are the most ubiquitous pro-chiral functional groups accessible to synthetic chemists. For this reason, difunctionalization reactions of alkenes are particularly important, as they can be used to access highly complex molecular architectures.1,2 Stereoselective oxidation reactions, including dihydroxylation, aminohydroxylation and halogenation reactions,3,4,5,6 are well-established meth...
متن کاملCopper-catalyzed three-component coupling of arynes, terminal alkynes and activated alkenes.
The three-component coupling of benzynes with terminal alkynes and activated alkenes in the presence of CuI, PCy(3) and CsF in a 1:1 mixture of CH(3)CN and THF at 50 degrees C for 5 h gave 1-alkyl-2-alkynylbenzenes in good to moderate yields.
متن کاملIodine-catalyzed three-component oxysulfenylation of alkenes with sulfonyl hydrazides and alcohols.
An unprecedented three-component oxysulfenylation reaction of alkenes with sulfonyl hydrazides and alcohols has been developed in the presence of 20 mol% iodine to give a range of structurally diverse β-alkoxy sulfides in good to excellent yields.
متن کاملAn efficient LDH-Pd-catalyzed three-component coupling of aryl iodides, alkynes and alkenes
A three-component coupling of aryl iodides, alkynes, and alkenes to generate 1,3-butadiene derivatives using layered double hydroxides supported nanopalladium (LDH-Pd) catalyst is described. LDH-Pd was recovered quantitatively by simple filtration and reused several times with almost consistent activity. 2006 Elsevier B.V. All rights reserved.
