Wacker-type oxidation of internal alkenes using Pd(Quinox) and TBHP

J Org Chem. 2013 Feb 15;78(4):1682-6. doi: 10.1021/jo302638v. Epub 2013 Feb 6.

Abstract

The Pd-catalyzed TBHP-mediated Wacker-type oxidation of internal alkenes is reported. The reaction uses 2-(4,5-dihydro-2-oxazolyl)quinoline (Quinox) as ligand and TBHP(aq) as oxidant to deliver single ketone constitutional isomer products in a predictable fashion from electronically biased olefins. This methodology is showcased through its application on an advanced intermediate in the total synthesis of the antimalarial drug artemisinin.
