DNA Encoded Libraries have proven immensely powerful tools for lead identification. The ability to screen billions of compounds at once has spurred increasing interest in DEL development and utilization. Although DEL provides access to libraries of unprecedented size and diversity, the idiosyncratic and hydrophilic nature of the DNA tag severely limits the scope of applicable chemistries. It is known that biomacromols. can be reversibly, noncovalently adsorbed and eluted from solid supports, and this phenomenon has been utilized to perform synthetic modification of biomols. in a strategy we have described as reversible adsorption to solid support (RASS). Herein, we present the adaptation of RASS for a DEL setting, which allows reactions to be performed in organic solvents at near anhydrous conditions opening previously inaccessible chem. reactivities to DEL. The RASS approach enabled the rapid development of C(sp2)-C(sp3) decarboxylative cross-couplings with broad substrate scope, an electrochem. amination (the first electrochem. synthetic transformation performed in a DEL context), and improved reductive amination conditions. The utility of these reactions was demonstrated through a DEL-rehearsal in which all newly developed chemistries were orchestrated to afford a compound rich in diverse skeletal linkages. We believe that RASS will offer expedient access to new DEL reactivities, expanded chem. space, and ultimately more drug-like libraries. In the experiment, the researchers used many compounds, for example, 1H-Benzo[d][1,2,3]triazol-1-amine (cas: 1614-12-6Category: triazoles).
1H-Benzo[d][1,2,3]triazol-1-amine (cas: 1614-12-6) belongs to triazole derivatives. The triazole ring is a relatively stable functional group, and the triazole bond can be used for a variety of applications, such as replacing the phosphate backbone of DNA.Triazole heterocyclic structures are found to form many weak nonbond interactions with the receptors and enzymes in biological systems.Category: triazoles
