Synthesis and antibacterial activity of new lactone 1,4-dihydroquinoline derivatives

In this work, a series of lactone 1,4-dihydroquinoline derivatives 4 were efficiently synthesized and characterized by 1H and 13C NMR. The synthesized compounds were evaluated for their in vitro antibacterial activity against the bacterial strains Porphyromonas gingivalis, Prevotella nigrescens, Streptococcus mitis, and Streptococcus sanguinis and against Mycobacterium tuberculosis, Mycobacterium avium and Mycobacterium kansasii. The results revealed that the evaluated compounds were more active against Gram negative bacteria. Compounds 4ba, 4bb, 4bg, 4bi, 4bn, 4ch, and 4ci displayed moderate antibacterial activity against P. gingivalis. 4bi was the most active compound against the three strains of Mycobacterium. Based on structure?activity relationship studies, we observed that the presence of a nitro group on the benzylic ring and a methylenedioxy group on the dihydroquinoline ring enhanced the antibacterial activity of the derivatives.

ZnCl2 supported on Fe3O4@SiO2 core?shell nanocatalyst for the synthesis of quinolines via Friedlaender synthesis under solvent-free condition

A magnetic nanocatalyst of Fe3O4@SiO2/ZnCl2 was prepared by supporting ZnCl2 on silica-coated magnetic nanoparticles of Fe3O4. This recoverable catalyst was used for the synthesis of quinolines via Friedlaender synthesis from 2-aminoaryl ketones and alpha-methylene ketones under solvent-free condition. The prepared catalyst was characterized by FT-IR, TEM, SEM, XRD, EDX, ICP-OES, VSM and BET. It was found that Fe3O4@SiO2/ZnCl2 showed higher catalytic activity than homogenous ZnCl2, and could be reused several times without significant loss of activity.

A DFT study on mechanisms of CO2 coupling with propargylic alcohols using alkali carbonates

The mechanisms of CO2 coupling with the propargylic alcohol using alkali carbonates M2CO3 (M = Li, Na, K, Cs) have been investigated by means of density functional theory calculations. The calculations reveal that the target product tetronic acid (TA) is yielded through two stages: (a) the formation of the alpha-alkylidene cyclic carbonate (alphaACC) intermediate via Cs2CO3-mediated carboxylative cyclization of the propargylic alcohol with CO2, and (b) the conversion of the alphaACC intermediate with Cs2CO3 to produce the cesium salt of the TA. Since the overall kinetic barriers for the two stages are comparable and affordable, the excellent chemoselectivity to the TA should be primarily originated from the high thermodynamic stability of the cesium salt of the TA. Moreover, relative to the TA, the possibility to yield the by-product acyclic carbonate can be excluded due to the both kinetics and thermodynamic inferiority. This result is different from the organic base-mediated reaction. Alternatively, our calculations predict that CsHCO3 together generated with the cesium salt of the TA might also be an available mediating reagent for the incorporation of CO2 with the propargylic alcohol. Compared to other alkali carbonates M2CO3 (M = Li, Na, K), the stronger basicity of Cs2CO3 and the lower ionic potential of cesium ion can raise the effective concentration of the alphaACC intermediate, and thus the conversion of the alphaACC intermediate into the cesium salt of the TA can be achieved with high yield.

Enantiomerically pure gamma-butyrolactones in natural products synthesis

Stereochemically defined gamma-butyrolactones have served as key building blocks in the syntheses of many types of natural products, including alkaloids, macrocyclic antibiotics, lignan lactones, pheromones, anti-leukemics, and flavor components. Accordingly, there are a large number of methods for the enantioselective preparation of substituted gamma-butyrolactones: from simple natural products such as amino acids, tartaric acid, ascorbic acids, carbohydrates, or ribonolactones; from chiral sulfoxides, epoxides, or substituted acetylenic acids; and by various enzymatic or synthetic reductions, oxidations, and hydrolyses. This review will summarize these enantioselective methods of lactone synthesis and for each briefly show how the resultant lactone fits into the synthetic scheme for a particular natural product synthesis.
