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 biomacromolecules can be reversibly, noncovalently adsorbed and eluted from solid supports, and this phenomenon has been utilized to perform synthetic modification of biomolecules 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 chemical reactivities to DEL. The RASS approach enabled the rapid development of C(sp(2))-C(sp(3)) decarboxylative cross couplings with broad substrate scope, an electrochemical amination (the first electrochemical 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 chemical space, and ultimately more drug-like libraries.

A copper-catalyzed regioselective net hydroamination of 1-trifluoromethylalkenes with hydrosilanes and hydroxylamines has been developed. The judicious choice of ligand and additive suppresses the conceivable but undesired beta-F elimination of an alpha-CF3-substituted organocopper intermediate, leading to targeted alpha-trifluoromethylamines in good yields with excellent regioselectivity. Additionally, with an appropriate chiral bisphosphine ligand, the enantioselective reaction is also possible to deliver optically active alpha-trifluoromethylamines of high potential in medicinal and pharmaceutical chemistry.

We report a highly chemoselective palladium-catalyzed Catellani-type amination of aryl iodides terminated by the Heck reaction using allylic esters as terminating reagents. 2-Aminocinnamyl esters were formed exclusively via beta-H elimination rather than beta-OAc elimination without the assistance of a silver salt. This protocol represents a useful extension of Catellani-type transformations.

An acid-free N-nitrosation/nitration of the N-H bonds in secondary amines with Fe(NO3)(3)center dot 9H(2)O as the nitroso/nitro source through an electrocatalyzed radical coupling reaction was developed. Cyclic aliphatic amines and N-heteroaromatic compounds were N-nitrosated and N-nitrated, respectively, under mild conditions. Control and competition experiments, as well as kinetic studies, demonstrate that N-nitrosation and N-nitration involve two different radical reaction pathways involving N+ and N-center dot radicals. Moreover, the electrocatalysis method enables the preferential activation of the N-H bond over the electrode and thus provides high selectivity for specific N atoms. Finally, this strategy exhibits a broad scope and provides a green and straightforward approach to generate useful N-nitroso/nitro compounds in good yields.

Oxidative carbonylation using CO/O-2 is an attractive strategy to construct carbonyl compounds, but the explosive limit of the gas mixture hampers its application. Now, this safety issue is overcome in the aminocarbonylation of alkynes by replacing the external oxidant O-2 by electrochemistry facilitating a mild and safe reaction. Palladium-catalysed oxidative carbonylation using oxygen as the oxidant is an economical approach; however, the gas mixture of CO and air has an explosive limit of 12.5-74.0% that could hamper extensive application of this process. Herein we report an electrochemical aminocarbonylation of alkynes under atmospheric pressure in an undivided cell without an external oxidant. The transformation has a broad substrate scope (83 examples) that involves primary amines and ammonium salts. Furthermore, mechanistic studies through cyclic voltammetry, in situ infrared and quick-scanning X-ray absorption fine structure spectroscopy reveal the reasons for this protocol proceeding smoothly under electrochemical conditions.

Highly functionalized 4-aminoindoles were synthesized via the three-component cross-coupling of o-iodoaniline, N-benzoyloxyamines, and norbornadiene. The Catellani and retro-Diels-Alder strategy was used in this domino process. o-Iodoaniline, with electron-donating and sterically hindered protecting groups, made the reaction selective toward o-C-H amination. On the basis of density functional theory calculations, the intramolecular Buchwald coupling of this reaction underwent a dearomatization and a 1,3-palladium migration process. The reasons for the control of the chemical selectivity by the protecting groups are given. Moreover, synthetic applications toward 4-piperazinylindole and a GOT1 inhibitor were realized.

A copper-catalyzed oxalamide-directed ortho-C-H amination of anilines has been developed by using 1 atm of air as the sole oxidant. The protocol shows excellent functional group tolerance, and some heterocyclic amines including indole, benzothiophene, benzothiazole, quinoline, isoquinoline, and quinoxaline could be compatible in the reaction. The late-stage diversification of medicinal drugs demonstrates the synthetic utility of this protocol.
