Clean Synthesis

The analogs of nitrogen-based heterocycles occupy an exclusive position as a value of more than 75% of drugs approved by the FDA and currently available in the market are nitrogen-containing heterocyclic moieties. Among many N-containing heterocycles, quinolines have become important due to their variety of applications in medicinal, synthetic organic chemistry as well as in the field of industrial chemistry. Present work gives information about the green and clean synthesis using multicomponent reactions (MCRs) methods and L-proline and ammonium acetate as a catalyst for the synthesis of quinoline derivatives. Synthesized quinoline derivatives undergo spectroscopic analysis and their biological evaluation.

Tetrasubstituted Imidazoles

The synthesis of novel 1,2,4,5-tetrasubstituted imidazoles was carried out in a single molecular motif using niobia supported heteropoly tungstate as a mild and efficient reusable catalyst. The condensation of 3-aryl-1-phenyl-1H-pyrazole-4-carbaldehyde, aromatic amine, benzil, ammonium acetate and heteropoly tungstate supported on niobia was achieved under both conventional and non-conventional conditions. The employed protocol provides significant advantages, as it exhibits a remarkable catalytic activity on recovery, excellent yields and excellent reaction efficacy within short reaction times between 1-2 h (conventional) and 1-3 min (microwave radiation). All the obtained compounds were characterized by means of spectral data and elemental analysis. They were also screened for their antibacterial activity. To predict the binding mode of compounds with glutamine-fructose-6-phosphate transaminase (GlcN6P synthase), docking studies were performed.

One of the major challenges in contemporary synthetic organic chemistry is the design and development of new tactics and strategies and their application to concise and efficient syntheses of biologically active natural products. Strategies that utilize reactions that enable the rapid assembly of the skeletal framework of such targets are thus especially attractive. In this context, we have developed novel applications of imine chemistry in Mannich and related reactions, cascade processes, and multicomponent reactions (MCRs) to rapidly assemble structural subunits common to diverse families of alkaloids. The practical utility of these chemistries is evidenced by their use in the execution of facile total syntheses of (±)-epilupinine (1), (±)-tashiromine (2), (-)-epimyrtine (3), and (±)-roelactamine (4) as well as other nitrogen heterocycles of potential biological interest.

Etoac Extract

The chemical investigation of the EtOAc extract of the fresh flowers of Juglans regia L. resulted in a new α-tetralonyl glucoside (1) and two known glucosides (2-3). The structure of the new compound was determined by extensive 1D and 2D NMR spectroscopic analysis and HRESIMS. The biological evaluation of the obtained glucosides showed that compound 1 and 3 displayed good antioxidant and antibacterial activities. These two compounds were identified as the main functional molecules in the fresh flowers of Juglans regia L.
