orane/sodium trifluoroacetate (BTPP/NaTFA) “dual-base” system in combination with an air-stable Ni(II) precatalyst containing either CyPAd-DalPhos or PhPAd-DalPhos. These catalyst systems enable access to a reaction scope that encompasses a range of challenging oxidative addition partners, including (hetero)aryl chlorides as well as pivalates, tosylates, and other related phenolderivatives.

Abstract2,5‐Disubstituted oxazoles with a variety of alkyl and aryl groups are efficiently formed from N‐acylamino acids, by a one‐pot radical decarboxylation–oxidation–enolization and iodine‐promoted cyclization process. Remarkably, the reaction takes place under mild conditions, and no metal catalysis is needed. The process can be useful for the direct modification of small peptides.magnified image
