The functionalization of aminoheterocycles by using a pyrylium tetrafluoroborate reagent (Pyry‐BF4) is presented. This reagent efficiently condenses with a great variety of heterocyclic amines and primes the C−N bond for nucleophilic aromatic substitution. More than 60 examples for the formation of C−O, C−N, C−S, or C−SO2R bonds are disclosed herein. In contrast to C−N activation through diazotization
An active, general, and long-lived palladium catalyst for Suzuki-Miyaura reactions of aryl and heteroaryl chlorides deactivated by steric hindrance, electron richness, and coordinating functional groups is reported. In reactions of arylbromide bearing two o-tert-butyl substituents, C(sp(3))-H arylation of the tert-butyl group, rather than the Suzuki-Miyaura reaction, proceeded in excellent yield. The key to the success of the reactions was the development of biphenylene-substituted dicyclohexylruthenocenylphosphine (CyR-Phos) as a supporting ligand.

This invention describes a class of compounds able to activate the human SIRT1 enzyme and regulate many metabolic functions. This invention relates to compounds that can be employed in medical applications, specifically for the treatment or prevention of cardiometabolic diseases, such as diabetes, and of cardiovascular disorders, such as coronaropathy, heart failure and atherosclerosis.
