چکیده

2-Allyl-substituted thiophenes and furans are synthesised efficiently in a direct procedure using 2-heteroaryllithium reagents and allyl bromides and chlorides catalysed by ligand-free copper(i). The reactions take place under mild conditions, with excellent α-selectivity, high functional group tolerance and good yields for the SN2 products.

University of Groningen Synthesis of Optically Active beta- or gamma-Alkyl-Substituted Alcohols through Copper-Catalyzed Asymmetric Allylic Alkylation with Organolithium Reagents

An efficient one-pot synthesis of optically active β-alkyl-substituted alcohols through a tandem coppercatalyzed asymmetric allylic alkylation (AAA) with organolithium reagents and reductive ozonolysis is presented. Furthermore, hydroboration−oxidation following the Cucatalyzed AAA leads to the corresponding homochiral γalkyl-substituted alcohols.

Tuneable asymmetric copper-catalysed allylic amination and oxidation reactions.

Asymmetric allylic amination or oxidation can be achieved by reaction of an alkene with a peroxycarbamate catalysed by a chiral copper bis-oxazoline complex, and the reaction can be tuned to give either the amination or oxidation product by reagent choice.
