Chiral Auxiliaries as Docking/Protecting Groups in Biohydroxylation:(S)-Specific Hydroxylation of Enantiopuretert-Butyl-Substituted Spirooxazolidines Derived From Cyclopentanone

The taming of oxygen: biocatalytic oxyfunctionalisations

The scope and limitations of oxygenases as catalysts for preparative organic synthesis is discussed.

Expanding the toolbox of organic chemists: directed evolution of P450 monooxygenases as catalysts in regio- and stereoselective oxidative hydroxylation

Cytochrome P450 enzymes (CYPs) have been used for more than six decades as catalysts for the CH-activating oxidative hydroxylation of organic compounds with formation of added-value products.

Specific 5-hydroxylation of piperlongumine by Beauveria bassiana ATCC 7159

A new hydroxylated derivative was efficiently prepared by transforming the natural anti-cancer product, piperlongumine, with Beauveria bassiana ATCC 7159. Its structure was determined to be 5-hydroxylpiperlongumine on the basis of the spectroscopic data. The absolute configuration at C-5 was established as R by Mosher's method.
