Chemo-enzymatic fluorination of unactivated organic compounds.

Fluorination has gained an increasingly important role in drug discovery and development. Here we describe a versatile strategy that combines cytochrome P450-catalyzed oxygenation with deoxofluorination to achieve mono- and polyfluorination of nonreactive sites in a variety of organic scaffolds. This procedure was applied for the rapid identification of fluorinated drug derivatives with enhance...

Enzymatic synthesis of carotenes and related compounds.

Data are presented in this paper which establish many of the reactions involved in the biosynthesis of carotenes. Studies have shown that all of the enzymes required for the synthesis of acyclic and cyclic carotenes from mevalonic acid are present in plastids of tomato fruits. Thus, it has been demonstrated that a soluble extract of an acetone powder of tomato fruits converts mevalonic acid to ...
