Nickel-Catalyzed Esterification of Aliphatic Amides

Recent studies have demonstrated that amides can be used in nickel-catalyzed reactions that lead to cleavage of the amide C?N bond, with formation of a C?C or C?heteroatom bond. However, the general scope of these methodologies has been restricted to amides where the carbonyl is directly attached to an arene or heteroarene. We now report the nickel-catalyzed esterification of amides derived from aliphatic carboxylic acids. The transformation requires only a slight excess of the alcohol nucleophile and is tolerant of heterocycles, substrates with epimerizable stereocenters, and sterically congested coupling partners. Moreover, a series of amide competition experiments establish selectivity principles that will aid future synthetic design. These studies overcome a critical limitation of current Ni-catalyzed amide couplings and are expected to further stimulate the use of amides as synthetic building blocks in C?N bond cleavage processes.

Nanoscale synthesis and affinity ranking

Most drugs are developed through iterative rounds of chemical synthesis and biochemical testing to optimize the affinity of a particular compound for a protein target of therapeutic interest. This process is challenging because candidate molecules must be selected from a chemical space of more than 1060 drug-like possibilities 1, and a single reaction used to synthesize each molecule has more than 107 plausible permutations of catalysts, ligands, additives and other parameters 2 . The merger of a method for high-throughput chemical synthesis with a biochemical assay would facilitate the exploration of this enormous search space and streamline the hunt for new drugs and chemical probes. Miniaturized high-throughput chemical synthesis 3-7 has enabled rapid evaluation of reaction space, but so far the merger of such syntheses with bioassays has been achieved with only low-density reaction arrays, which analyse only a handful of analogues prepared under a single reaction condition 8-13 . High-density chemical synthesis approaches that have been coupled to bioassays, including on-bead 14, on-surface 15, on-DNA 16 and mass-encoding technologies 17, greatly reduce material requirements, but they require the covalent linkage of substrates to a potentially reactive support, must be performed under high dilution and must operate in a mixture format. These reaction attributes limit the application of transition-metal catalysts, which are easily poisoned by the many functional groups present in a complex mixture, and of transformations for which the kinetics require a high concentration of reactant. Here we couple high-throughput nanomole-scale synthesis with a label-free affinity-selection mass spectrometry bioassay. Each reaction is performed at a 0.1-molar concentration in a discrete well to enable transition-metal catalysis while consuming less than 0.05 milligrams of substrate per reaction. The affinity-selection mass spectrometry bioassay is then used to rank the affinity of the reaction products to target proteins, removing the need for time-intensive reaction purification. This method enables the primary synthesis and testing steps that are critical to the invention of protein inhibitors to be performed rapidly and with minimal consumption of starting materials.

Synthesis, crystal structures, insecticidal activities, and structure-activity relationships of novel N ?- Tert -Butyl- N ?-substituted-benzoyl- N -[di(octa)hydro]benzofuran{(2,3-dihydro)benzo[1, 3]([1,4])dioxine}carbohydrazide derivatives

Several series of novel N?-tert-butyl-N?-substituted-benzoyl-N- [di(octa)hydro]benzofuran{(2,3-dihydro)benzo[1,3]([1,4])dioxine}carbohydrazide derivatives Ia, Ib, IIa-IIg, IIIa, IIIb, and Va-Vc were designed and synthesized. Their structures were confirmed by 1H NMR spectra, HRMS, and X-ray single-crystal structures. The larvicidal activities against oriental armyworm, beet armyworm, diamond-back moth, and corn borer of these compounds were evaluated and contrasted with those of RH-2485, JS-118, and ANS-118. The larvicidal activities against oriental armyworm indicate that monosubstituent or multisubstituents and the substituting group position cannot promote increasing activities and that the cycle region in the general structure of IIa-IIg is much more sensitive to activity than that in the general structure of Ia and Ib. The space volume of the A ring in the structure of Va cannot be too large; if it is, the activity will be decreased significantly. Stomach toxicities against beet armyworm, diamond-back moth, and corn borer of compounds Ia, Ib and IIg indicate that benzoheterocyclic analogues of N-tert-butyl-N,N?- diacylhydrazines show significant selectivities to different lepidopterous pests.

TRPV1 modulators: Synthesis and in vitro evaluation of 1-heteroaryl piperidinecarboxamide and piperazinylurea derivatives

Abstract A series of new 1-heteroaryl piperidinecarboxamide and piperazinylurea derivatives was synthesized and evaluated as TRPV1 modulators in a Ca2+ channel assay in HEK-293 cells overexpressing the human recombinant TRPV1 channel. Structural variations in the putative key portions of the molecules afforded several compounds endowed with agonist and/or antagonist/desensitizing activity at low micromolar concentration. As promising examples from this series, the piperidine-3-carboxamide derivative 31 exerts agonist/desensitizing activity at low micromolar concentration, while piperazinylurea derivatives 39 and 41 act as antagonists with sub-micromolar potency.

Copper-Catalyzed Regioselective Hydroalkylation of 1,3-Dienes with Alkyl Fluorides and Grignard Reagents

Copper complexes generated in situ from CuCl2, alkyl Grignard reagents, and 1,3-dienes play important roles as catalytic active species for the 1,2-hydroalkylation of 1,3-dienes by alkyl fluorides through C-F bond cleavage. The alkyl group is introduced to an internal carbon atom of the 1,3-diene regioselectively, thus giving rise to the branched terminal alkene product. Making the switch: A copper-hydride species, generated by the treatment of a copper salt with alkyl Grignard reagents, catalyzes the 1,2-hydroalkylation of 1,3-dienes by alkyl fluorides and Grignard reagents. The alkyl group of the alkyl fluoride is selectively introduced to an internal carbon atom of the 1,3-diene and the Grignard reagent acts as hydride source to give the branched terminal alkene, even in the presence of alkenes and alkynes.
