Designing new baeyer-villiger monooxygenases using restricted CASTing

This paper outlines the design and execution of the first mini-evolution of cyclopentanone monooxygenase (CPMO). The methodology described is a relatively inexpensive and rapid way to obtain mutant enzymes with the desired characteristics. Several successful mutants with enhanced enantioselectivities were identified. For example, mutant-catalyzed oxidation of 4- methoxycyclohexanone gave the corresponding lactone with 92% entantiometric excess (ee) compared to the 46% ee achieved with wild-type cyclohexanone monoxygenase (WT-CHMO). The original design of the mini-evolution and the following evaluation of mutants can provide valuable insights into the active site's construction and dynamics and can suggest other catalytically profitable mutations within the putative active site.

We present a mild way of converting secondary methyl ethers into ketones using calcium hypochlorite in aqueous acetonitrile with acetic acid as activator. The reaction is compatible with various oxygen- and nitrogen-containing functional groups and afforded the corresponding ketones in up to 98% yield. The use of this methodology could expand the application of the methyl group as a useful protecting group.

An in situ generated hypervalent iodine species, bis(tert-butylperoxy) iodobenzene, was used as a peroxy radical source for the oxidation of unreactive, remote, and isolated alkyl (cyclic or aliphatic) esters and amides to the corresponding keto compounds under very mild conditions.
