This report describes a carboxylate-assisted palladium-catalysed Catellani reaction, which is compatible with ortho-amination and unactivated C(sp(2))-H arylation. This method was used to synthesize a series of 1-amino substituted dihydrophenanthridines, phenanthridines and 6H-benzo[c]chromenes. Based on kinetic isotope experiments, the kinetic curve proves that pivalic acid accelerates the reaction rate of unactivated C(sp(2))-H activation, and thus this rate can keep up with the five membered aryl-norbornene-palladacycle (ANP) intermediate.

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.

An operationally simple oxidation cyanation method for the synthesis of cyanamides is described. The procedure utilizes inexpensive and commercially available N-chlorosuccinimide and Zn(CN)(2) as reagents to avoid direct handling of toxic cyanogen halides. It is demonstrated to be amenable for the cyanation of a variety of primary and secondary amines and aniline derivatives as well as a complex synthetic intermediate en route to verubecestat (MK-8931). Additionally, kinetic measurements and other control experiments are reported to shed light onto the mechanism of this cyanation reaction.

Indolecarboxamides are potent but poorly soluble mycobactericidal agents. Here we found that modifying the incipient scaffold by amide-amine substitution and replacing the indole ring with benzothiophene or benzoselenophene led to striking (10-20-fold) improvements in solubility. Potent activity could be achieved without the carboxamide linker but not in the absence of the indole ring. The indolylmethylamine, N-cyclooctyl-6-trifluoromethylindol-2-ylmethylamine (33, MIC90Mtb , 0.13 mu M, MBC99.9Mtb, 0.63 mu M), exemplifies a promising member that is more soluble and equipotent to its carboxamide equivalent. It is also an inhibitor of the mycolate transporter MmpL3, a property shared by the methylamines of benzothiophene and benzoselenophene.

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.

The generation of aminium radical cation species from N-nitrosoamines is disclosed for the first time through visible-light excitation at 453 nm. The developed visible-light-promoted photoaddition reaction of N-nitrosoamines to alkenes was combined with the o-NQ-catalyzed aerobic oxidation protocol of amines to telescope the direct handling of harmful N-nitroso compounds, where the desired aamino oxime derivatives were obtained in a one-pot tandem Nnitrosation and photoaddition sequence.

A copper-catalyzed protocol has been realized for the rapid assembly of dihydroquinolinones from readily accessible isocyanides and O-benzoyl hydroxylamines. The reactions (10 mol % of CuOAc, 10 mol % of dppe, 3 equiv of PhONa, 30 degrees C) deliver various structurally interesting dihydroquinolinones in moderate to good yields (up to 76%). The reactions may proceed in a cascade manner involving isocyanide insertion into the N-O bond, Mumm-type rearrangement, and intramolecular nucleophilic substitution.

In the present study, the partly and fully-substituted monospiro (4-6, 4a-6d), cis-dispiro (7-9), trans-dispiro (10-15) cyclotriphosphazenes were synthesized for the investigations of their chemical, stereogenic and biological properties. The cis/trans phosphazenes (7-12) have two stereogenic P centers. They are expected to be in meso and racemic forms. In addition, the structures of four compounds were evaluated using X-ray crystal-lographic data. Compound 13 was found to be a single enantiomer (RR) in the solid state, as also proved with its CD spectrum. The antibacterial and antifungal activities of the phosphazenes were elucidated for against Gram-positive (G+) and Gram-negative (G-) bacteria, and yeast strains, respectively. Of the compounds, 14 exhibits strong antimicrobial activity against most of the tested organisms, especially B. cereus and E. hirae. MBC and MFC values of compounds on different bacterial and fungal species ranged from < 9.8 mu M to 2500 mu M. Furthermore, the cytotoxic activities of 6, 4c, 10 and 14 were investigated against L929 fibroblast and DLD-1 cells, and 14 was the most cytotoxic compound against DLD-1. HPLC of Formula: C7H13NO2.

A modular continuous flow synthesis of imatinib and analogues is reported. Structural y diverse imatinib analogues are rapidly generated using three readily available building blocks via a flow hydration/chemoselective C-N coupling sequence. The newly developed continuous flow hydration and amidation modules each exhibit a broad scope with good to excellent yields. Overall, the method described does not require solvent switches, in-line purifications, or packed-bed apparatuses due to the judicious manipulation of flow setups and solvent mixtures.
