the basis of sequential azide–aryne and azide–alkyne cycloadditions. The key to success was efficient halogen–metalexchange reaction-mediated generation of aryne from ortho-iodoaryl triflates bearing a base-sensitive terminal alkyne moiety, which was achieved using trimethylsilylmethyl Grignardreagent.

A sequential copper-catalyzed, one-pot, click reaction–intramolecular direct arylation, which involves two mechanistically distinct reactions (atom-economical clickreaction and direct arylation of 1,2,3-triazole), to generate [6,6]-, [6,7]-, [6,8]-, and [6,9]ring-fusedtriazoles is reported. Furthermore, a unique divergence of reactivity between the fusedtriazoles prepared from 2-bromobenzyl azide

A new series of mollugin-1,2,3-triazole derivatives were synthesized using a copper(I)-catalyzed Huisgen 1,3-dipolar cycloaddition reaction of corresponding O-propargylated mollugin with aryl azides. All the compounds were evaluated for their cytotoxicity on five human cancer cell lines (HL-60, A549, SMMC-7721, SW480, and MCF-7) using MTS assays. Among the synthesized series, most of them showed cytotoxicity

The present disclosure provides fluorogenic azide compounds. Also provided are methods of using the subject compounds for labelling a target biomolecule that includes an alkyne. In some embodiments, the method includes contacting the biomolecule with a fluorogenic azide compound, wherein the contacting results in covalent linkage of the compound with the alkyne moiety of the target biomolecule.

in human diseases such as colorectal cancer and Alzheimer’sdisease, supporting the need to discover improved inhibitors, especially for use in models of neurodegeneration. Here, we have described the discovery and profile of 8l (ARUK3001185) as a potent, selective, and brain-penetrant inhibitor of Notum activity suitable for oral dosing in rodent models of disease.
