Catalyst Calls The Shots - Organic Synthesis: Iron-based catalyst controls selectivity in C–H oxidations

A reaction scheme showing Fe(PDP), top, and Fe(CF3-PDP) catalysts selectively oxidizing different C–H bonds (yellow and green) in the same isoleucine substrate.
Iron catalysts selectively oxidize different C–H bonds (yellow and green) in the same isoleucine substrate, reactions that would otherwise require independent synthetic routes from different starting materials.

Chemists have developed a new catalyst that accelerates oxidation of C–H bonds selectively in nonaromatic compounds such as terpenes, rather than relying on the inherent properties of the reactant molecules. The catalyst could boost the versatility with which organic compounds can be synthesized for drug discovery and other applications.
