Abstract

The biocatalytic employment of modular polyketide synthase enzymes in cell lysate has become a viable route to preparative quantities of synthetically valuable polyketide fragments. We report the quantitative, uninvasive, and continuous monitoring of such biocatalytic reactions by observing trifluoromethyl-bearing substrates via 19F NMR spectroscopic analysis. To demonstrate the utility of this technique, we followed reactions catalyzed by a thioesterase and several ketoreductases.
