A rhodium-catalyzed annulative reaction between azobenzenes and nitrosoarenes has been developed, leading to a series of phenazines in moderate to good yields. This procedure proceeds with sequential chelation-assisted addition of aryl C–H to nitrosoarenes and ring closure by electrophilic attack of azo group to aryl. During this transformation, the azo group served as not only a traceless directing

Provided are oxyntomodulin analogs. The peptide analogs have at least two cysteines. The two cysteines are separated by six amino acids such that they can be crosslinked using suitable crosslinking moieties. The crosslinked peptides have long half-lives and/or efficacy. For example, peptide analog compositions are used for inducing weight loss and/or reducing blood glucose levels.
the highest selectivity for the TX mismatches, as these macrocycles show no apparent binding to the fully paired DNA. By contrast, other macrocyclicligands, as well as seven conventional DNA binders, show lesser or no selectivity for the mismatch sites. The study demonstrates that the topology of the ligands plays a crucial role in determining the mismatch‐binding affinity and selectivity of the macrocyclic

A silver-mediated annulation between arylcarbamic acids and nitrosoarenes was developed, leading to phenazines in moderate to good yields with complexity and diversity. This procedure proceeded with the sequential ortho CH functionalization of arylcarbamic acids, insertion to nitroso group and decarboxylative annulation.
