Exploring substrate scope and stereoselectivity of P450 peroxygenase OleT JE in olefin-forming oxidative decarboxylation

As recently reported, the olefin-forming oxidative decarboxylation of straight-chain C4-C22 carboxylic acids catalyzed by P450 peroxygenase OleTJE constitutes a mild alkene synthesis. The present study shows that structurally different carboxylic acids are also accepted, including those that generate di-substituted olefins. Exploratory mutational experiments lead to increased trans-selectivity.
