A copper-catalyzed asymmetric Friedel–Crafts propargylic alkylation of electron-rich phenol derivatives with a variety of propargylic esters has been described. With Cu(OTf)2 decorated with a chiral tridentate ketimine P,N,N-ligand as the catalyst, asymmetric Friedel–Crafts propargylic alkylation of 3,5-dialkoxyphenol derivatives proceeded smoothly in high yields and with good to excellent enantioselectivities. The present study suggested that the presence of an electron-rich substituent on the meta-position of phenol is essential for the promotion of Friedel–Crafts propargylic alkylation, and the substrate bearing two electron-rich groups on both the 3,5-positions of phenol tends to give a satisfactory performance.

Organic & Biomolecular Chemistry (OBC) publishes original and high impact research and reviews in organic chemistry. We welcome research that shows new or significantly improved protocols or methodologies in total synthesis, synthetic methodology or physical and theoretical organic chemistry as well as research that shows a significant advance in the organic chemistry or molecular design aspects of chemical biology, catalysis, supramolecular and macromolecular chemistry, theoretical chemistry, mechanism-oriented physical organic chemistry, medicinal chemistry or natural products. Articles published in the journal should report new work which makes a highly-significant impact in the field. Routine and incremental work is generally not suitable for publication in the journal. More details about key areas of our scope are below. In all cases authors should include in their article clear rationale for why their research has been carried out.
