SylC catalyzes ureido-bond formation during biosynthesis of the proteasome inhibitor syringolin A

(Chemical Equation Presented) Syringolins are a class of cyclic tripeptide natural products that are potent and irreversible inhibitors of the eukaryotic proteasome. In addition to being hybrid NRPS/PKS molecules, they also feature an unusual ureido-linka

Transition Metal-Free N-Arylation of Amino Acid Esters with Diaryliodonium Salts

A transition metal-free approach for the N-arylation of amino acid derivatives has been developed. Key to this method is the use of unsymmetric diaryliodonium salts with anisyl ligands, which proved important to obtain high chemoselectivity and yields. The scope includes the transfer of both electron deficient, electron rich and sterically hindered aryl groups with a variety of different functional groups. Furthermore, a cyclic diaryliodonium salt was successfully employed in the arylation. The N-arylated products were obtained with retained enantiomeric excess.
