A convenient and efficient strategy for the synthesis of 2-acyl benzothiazoles/thiazoles has been developed. The treatment of benzothiazole/thiazole with allylic Grignard reagents readily generates the corresponding 2-Grignard reagents, which is followed by a reaction with N,N’-carbonyldiimidazole activated carboxylic acids to afford various 2-acyl benzothiazoles/thiazoles products. The synthetic method is applicable to a wide array of carboxylic acids and allows easy access to 2-acyl benzothiazoles/thiazoles with considerable yields under mild reaction conditions.

The development of sub-nanometric metal particles (<1 nm) as advanced heterogeneous catalysts has received considerable interest due to their outstanding catalytic performance, while the synthesis and stabilization of sub-nanometric catalysts (SNCs) without using additional surface capping agents remains a challenge. Herein, we report the synthesis of novel three-dimensional pyrenyl graphdiyne (Pyr-GDY) ultrafine nanofibers (3-10 nm), which can serve as an ideal substrate for electroless deposition and stabilization of Pd SNCs through the terminal uncoupled acetenyl groups in Pyr-GDY, with an average Pd particle size of only 0.83 nm. The as-synthesized Pd/Pyr-GDY composite shows extremely high catalytic activities for the reduction of nitroarenes to arylamines and Suzuki coupling reactions, 300 and 25 times higher than those of commercial Pd/C, respectively. The outstanding catalytic performance can be ascribed to the sub-nanometric Pd particles with a clean surface, and the unique three-dimensional network structure of Pyr-GDY, being favorable for rapid mass transfer. Our result provides an ideal carbon material for electroless deposition and stabilization of other SNCs with a clean surface, which will display outstanding catalytic activity for various catalytic reactions.

Overexpression of aldehyde dehydrogenase 1A1 (ALDH1A1) is associated with the occurrence and development of obesity and insulin resistance. Herein, a series of coumarin-based ALDH1A1 inhibitors were designed, synthesized and evaluated. Among them, compounds 10, 14 and 26 exhibited potent inhibitory activity against ALDH1A1 and high selectivity over ALDH1A2, ALDH1A3, ALDH2 and ALDH3A1. Optimized compound 10 showed markedly improved pharmacokinetic characters and ADME profiles comparing to the lead compound 1. In vitro study demonstrated that 10 alleviated palmitic acid-induced impairment of glucose consumption in HepG2 cells. (C) 2019 Elsevier Masson SAS. All rights reserved.

A site-selective supported palladium nanoparticle catalyzed Suzuki-Miyaura cross-coupling reaction with heteroaryl esters and arylboronic acids as coupling partners was developed. This methodology provides a heterogeneous catalytic route for aryl ketone formation via C(acyl)-O bond activation of esters by successful suppression of the undesired decarbonylation phenomenon. The catalyst can be reused and shows high activity after eight cycles. The XPS analysis of the catalyst before and after the reaction suggested that the reaction might be performed via a Pd-0/Pd-II catalytic cycle that began with Pd-0.

10-(1-Phthalazinylazo)-9-phenanthrol (HL, I) was synthesized by the reaction between 1-hydrazinophthalazine and 9,10-phenanthrenequinone. The crystal and molecular structures of compound I were determined by X-ray diffraction (XRD). According to XRD, EAS, and H-1 and C-13 NMR data, a HL molecule in solutions and in crystals exists in the form of quinohydrazone tautomer (b) (s-trans, cis) stabilized by intramolecular N(3)H…O(1) hydrogen bond. The mobile H atom is localized at the N(3) atom of the azo group. The phthalazine (A) and phenanthrenequinone (B) moieties of the HL molecule are nearly coplanar. The HL basicity and acidity constants (pK(a) = 1.90 and pK(a) = 11.65, respectively) and the formation constants of HL complexes with Zn2+ and Cd2+ and their compositions in solutions were determined. ML2 center dot DMFA complexes, where M = Zn2+, Cd2+, were synthesized. The coordination mode of the L- ligand with metal atoms was suggested.

A systematic study of the reaction of 1,4-dihydrazinophthalazine (DHPH) with 1,3-dicarbonyls [viz., acetylacetone (acac), dibenzoylmethane (bzbz), and 1-benzoylacetone (bzac)] varying the reaction conditions was carried out to obtain the phthalazine derivatives (1-4). One-pot reaction of DHPH with acac led to the formation of two compounds 1 and 2, with various factors such as the presence of the acid or base, amount of the acac, time of reflux, and the temperature. The reaction conditions of DHPH with bzbz or bzac are sort of different to isolate the products 3 and 4, respectively. The derivatives (1-4) have been characterized by elemental analyses, H-1 NMR, and electrospray ionization-mass spectrometry (ESIMS) and the cytotoxic activity of the compounds 1-4 was evaluated on HeLa cell line.
