Distance-Dependent Chiral Communication between Two Quinoline Oligoamide Foldamers Connected by Alkyl Chains

A series of macrocycles that contain two quinoline oligoamide foldamers (QOFs) using various length of alkyl chains as linkers (2, 3, 6, 8 or 12 hydrocarbons) were synthesized. The two QOFs interact with each other through the linkers and the intramolecular helix chiral communications between the two QOFs were studied by H-1 NMR spectroscopy and crystal structures. Investigations show that the intensity of the intramolecular helix chiral communications between the two QOFs is dependent on the length of the linkers, and the interaction between the two QOFs increases with decreasing length of the linkers. When the length of the linkers decreased to C2 linkers, only one conformer is present in solution. Moreover, increasing the length of the foldamers would enhance the intramolecular helix chiral communication if the linkers are short, indicating that the length of the foldamers also has significant impact on intramolecular helix chiral communication.

Copper-catalyzed [3+2+1] annulation of anthranils with phenylacetaldehydes: Synthesis of 8-acylquinolines

A Cu-0-catalyzed protocol is proposed for the synthesis of 8-acylquinolines through a [3+2+1] annulation starting from anthranils and phenylacetaldehydes. This protocol is of particular interest in preparing 8-aldehyde quinolines, which have been hard to access so far. Both AgOTf and dioxygen played an important role in the reaction. C3-heterocycle or phenylethylene substituted anthranils could also be employed in the reaction. An interesting esterification of aldehyde was observed.

Blueberry, raspberry, and strawberry extracts reduce the formation of carcinogenic heterocyclic amines in fried camel, beef and chicken meats

Heterocyclic amines (HCAs) are toxic products from the Maillard reaction that form from the reaction of sugars, amino acids and creatine/creatinine when cooking protein rich food. In this work, commonly consumed meats in Saudi Arabia (camel, beef and chicken) were fried under conditions resembling home cooking. The effect of marinades made of blueberry, raspberry and strawberry were tested separately on meat at different marinating times (1, 6, 12, 24h, at 4 degrees C) before frying. The marinades caused an overall reduction of HCAs. The decrease was more noticeable with long marination time >= 6h. The reduction of individual HCAs, after 24h marinades, was 91-100% for pyridines; 40-67% for beta-carbolines; and 100% for quinoxalines, quinolines, alpha-carbolines and gamma-carbolines, although the latter three were seldomly detected in this study. An increase, up to 2 times, on the formation of the studied quinoxalines was observed in every meat and marination for no more than 1h. Therefore, longer marinating times with berry extracts, from 6h, are recommended over those below (1h).

Synthesis of polyfluorinated 4-hydroxyquinolin-2(1H)-ones based on the cyclization of 2-alkynylanilines with carbon dioxide

Convenient and efficient synthesis of polyfluorinated 4-hydroxyquinolin-2(1H)-ones from the corresponding oalkynylaniline derivatives and CO2 (1 atm), mediated by 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) and AgNO3 in acetonitrile was performed. This synthetic methodology may be used to prepare fluorinated heterocycles containing peripheral alkynyl and amino groups but is not suitable for silylethynyl derivatives that give indoles as the main products. The reaction takes place under mild conditions (60 degrees C) and involves readily available starting materials that include cheap and renewable carbon dioxide.

Quinoline-Proline, Triazole Hybrids: Design, Synthesis, Antituberculosis, Molecular Docking, and ADMET Studies

A series of novel quinoline-proline hybrids (11a-g) and quinoline-proline-1,2,3-triazole hybrids (12-14) were synthesized by click chemistry based on molecular hybridization concept and were characterized by NMR, mass spectrometry, and elemental analysis. All the titled target compounds were tested for antitubercular activity by MABA and LORA methods by in vitro. Interestingly, two compounds (2R,4S)-1-((2-cyclopropyl-4-(4-fluorophenyl)-quinolin-3-yl)-methyl)-4-(4-nitrobenzamido)-N-phenylpyrrolidine-2-carboxamide (11b) and (2R,4S)-1-((2-cyclopropyl-4-(4-fluorophenyl)-quinolin-3-yl)-methyl)-4-(4-fluorobenzamido)-N-phenylpyrrolidine-2-carboxamide (11c) exhibited significant activity against the tested Mycobacterium tuberculosis H37Rv strain. Further, the cytotoxicity (CC50) profile of the titled compounds against the Vero cell was performed and discussed. A molecular docking study of the hit compounds (11b and 11c) was also performed to find their putative binding interaction with the active site of the target proteins. Finally, in silico ADMET properties were also predicted for all the synthesized molecules to evaluate their drug-likeness behavior.

Waste-minimized synthesis of C2 functionalized quinolines exploiting iron-catalysed C-H activation

Herein we present an efficient and regioselective iron-catalyzed methodology for the external oxidant-free functionalization of quinoline-N-oxides. The protocol, based on the use of inexpensive and easily accessible FeSO4, showed broad applicability to a wide range of substrates. An additional green feature of this synthetic methodology is H2O being the only by-product. Experimental and computational investigations provide support to a mechanism based on a facile C-H activation event. The green efficiency of the process has also been carefully assessed using: (i) metrics related to the synthetic process (AE, Yield, 1/SF, MRP and RME); (ii) safety/hazard metrics (SHZI and SHI); and (iii) metrics related to the metal used as the catalyst (Abundance, OEL and ADP). In addition to the many advantages of this protocol related to the green iron catalyst used and the safety/hazard features of the process, an E-factor value of ca. 0.92 (84 to >99% reduction compared to known protocols) evidently confirms the sustainable efficiency of the procedure presented. Practical utility has also been demonstrated by performing the reaction efficiently on a multi-gram scale.

Design and synthesis of a solvent-dependent fluorescent probe for dual selective detection of Mg2+ ion and Zn2+ ion

A solvent-dependent fluorescent probe QC for the dual detection of Mg2+ ion and Zn2+ ion has been constructed based on a Schiff base compound, in which 8-hydroxyquinoline served as not only a fluorophore but also a recognition group. Among the various tested metal ions, this probe exhibited high sensitivity and good selectivity toward Mg2+ ion in acetonitrile and Zn2+ ion in EtOH-H2O (9:1, v/v), respectively. With the treatment of Mg2+ ion or Zn2+ ion, 1:2 complex was formed between QC and Mg2+ ion, which inhibited the PET processes caused by the lone pair electrons from the nitrogen atom of the -C = N group and the nitrogen atom of quinoline moiety, resulting in the fluorescence enhancement for Mg2+ ion. Whereas a 1:1 complex was formed between QC and Zn2+ ion, which inhibited the PET process only caused by the lone pair electrons from the nitrogen atom of the -C = N group, resulting in the fluorescence enhancement at a shorter wavelength. The detection limit was calculated as low as 6.28 x 10(-8) M for Mg2+ ion and 2.36 x 10(-7) M for Zn2+ ion. DFT analysis further supported this concept to design the probe.

Catalyst- and Additive-Free Annulation of Ynediones and (Iso)Quinoline N-Oxides: An Approach to Synthesis of Pyrrolo[2,1-a]Isoquinolines and Pyrrolo[1,2-a]Quinolines

A simple and effective annulation of ynediones and (iso)quinoline N-oxides was developed to afford various functionalized pyrrolo[2,1-a]isoquinolines and pyrrolo[1,2-a]quinolines in moderate to excellent yields. This protocol underwent a tandem [3 + 2] cycloaddition/ring-opening/N-nucleophilic addition, which exhibited high regioselectivity, broad substrate tolerance, and atom economy under catalyst-, additive-free, and air conditions. Moreover, indolizine was also successfully prepared using pyridine N-oxide.
