Metal-catalyzed cross-coupling reactions are among the most important transformations in organic synthesis. However, the use of C-H activation for sp(2) C-N bond formation remains one of the major challenges in the field of cross-coupling chemistry. Described herein is the first example of the synergistic combination of copper catalysis and electrocatalysis for aryl C-H amination under mild reaction conditions in an atom-and step-economical manner with the liberation of H-2 as the sole and benign byproduct.

The cascade amination/cyclization ofN-arylacrylamides with alkyl amines under visible-light photoredox catalysis is realized via intermediacy of aminium radicals. The aminium radicals are generated by a two-step sequence which involves N-chlorination of alkyl amines and subsequent reductive N-Cl cleavage. This method provides a convenient access to aminated oxindoles.

A simple and facile copper(II) mediated protocol for C-8 amination of 1-naphthylamide derivatives is reported here. Picolinamide and its derivatives were used as a bidentate directing group for the C-8 amination reaction. Various substituted naphthylamide derivatives with numerous cyclic and acyclic amines proceed in good yields under mild conditions. Air was used solely as an oxidant. (C) 2021 Elsevier Ltd.

DNA encoded libraries (DEL) have shown promise as a valuable technology for democratizing the hit discovery process. Although DEL provides relatively inexpensive access to libraries of unprecedented size, their production has been hampered by the idiosyncratic needs of the encoding DNA tag relegating DEL compatible chemistry to dilute aqueous environments. Recently reversible adsorption to solid support (RASS) has been demonstrated as a promising method to expand DEL reactivity using standard organic synthesis protocols. Here we demonstrate a suite of on-DNA chemistries to incorporate medicinally relevant and C-S, C-P and N-S linkages into DELs, which are underrepresented in the canonical methods.

The first general palladium-catalyzed amination of aryl phosphates is described. The combination of MorDalPhos with [Pd(pi-cinnamyl)Cl](2) enables the amination of electron-rich, electron-neutral, and electron-poor aryl phosphates with a board range of aromatic, aliphatic, and heterocyclic amines. Common functional groups such as ether, keto, ester, and nitrile show an excellent compatibility in this reaction condition. The solvent-free amination reactions are also successful in both solid coupling partners. The gram-scale cross-coupling is achieved by this catalytic system.

Introduction Pressure support ventilation (PSV) should allow spontaneous breathing with a normal neuro-ventilatory drive. Low neuro-ventilatory drive puts the patient at risk of diaphragmatic atrophy while high neuro-ventilatory drive may causes dyspnea and patient self-inflicted lung injury. We continuously assessed for 12 h the electrical activity of the diaphragm (EAdi), a close surrogate of neuro-ventilatory drive, during PSV. Our aim was to document the EAdi trend and the occurrence of periods of Low and/or High neuro-ventilatory drive during clinical application of PSV. Method In 16 critically ill patients ventilated in the PSV mode for clinical reasons, inspiratory peak EAdi peak (EAdi(PEAK)), pressure time product of the trans-diaphragmatic pressure per breath and per minute (PTPDI/b and PTPDI/min, respectively), breathing pattern and major asynchronies were continuously monitored for 12 h (from 8 a.m. to 8 p.m.). We identified breaths with Normal (EAdi(PEAK) 5-15 mu V), Low (EAdi(PEAK) < 5 mu V) and High (EAdi(PEAK) > 15 mu V) neuro-ventilatory drive. Results Within all the analyzed breaths (177.117), the neuro-ventilatory drive, as expressed by the EAdi(PEAK), was Low in 50.116 breath (28%), Normal in 88.419 breaths (50%) and High in 38.582 breaths (22%). The average times spent in Low, Normal and High class were 1.37, 3.67 and 0.55 h, respectively (p < 0.0001), with wide variations among patients. Eleven patients remained in the Low neuro-ventilatory drive class for more than 1 h, median 6.1 [3.9-8.5] h and 6 in the High neuro-ventilatory drive class, median 3.4 [2.2-7.8] h. The asynchrony index was significantly higher in the Low neuro-ventilatory class, mainly because of a higher number of missed efforts. Conclusions We observed wide variations in EAdi amplitude and unevenly distributed Low and High neuro ventilatory drive periods during 12 h of PSV in critically ill patients. Further studies are needed to assess the possible clinical implications of our physiological findings.

Metal-catalyzed beta-C-H functionalization of saturated carbonyls via dehydrogenative desaturation proved to be a powerful tool for simplifying synthesis of valuable beta-substituted carbonyls. Here, we report a copper-catalyzed dehydrogenative gamma-C(sp(3))-H amination of saturated ketones that initiates the three-component coupling of saturated ketones, amines and N-substituted maleimides to construct polysubstituted anilines. The protocol presented herein enables both linear and alpha-branched butanones to couple a wide spectrum of amines and various N-substituted maleimides to produce diverse tetra- or penta-substituted anilines in fair-to-excellent yields with good functional group tolerance. The mechanism studies support that this ketone dehydrogenative gamma-C(sp(3))-H amination was triggered by the ketone alpha,beta-dehydrogenation desaturation that activates the adjacent gamma-C(sp(3))-H bond towards functionalization. This alpha,beta-dehydrogenation desaturation-triggered cascade sequence opens up a new avenue to the remote C(sp(3))-H functionalization of saturated ketones and has the potential to enable the rapid syntheses of complex compounds from simple starting materials.

In this study, we establish that conjugated enynes undergo selective 1,4-hydroamination under Pd catalysis to deliver chiral allenes with pendant allylic amines. Several primary and secondary aliphatic and aryl-substituted amines couple with a wide range of mono- and disubstituted enynes in a nonenantioselective reaction where DPEphos serves as the ligand for Pd. Benzophenone imine acts as an ammonia surrogate to afford primary amines in a two-step/one-pot process. Examination of chiral catalysts revealed a high degree of reversibility in the C-N bond formation that negatively impacted enantioselectivity. Consequently, an electron-poor ferrocenyl-PHOX ligand was developed to enable efficient and enantioselective enyne hydroamination.
