Opis:
Nanotechnology plays a pivotal role in all areas of science, and the synthesis and surface modification of nanoparticles are crucial in this field. Metal nanoparticles synthesized using plant extracts or phytocompounds are highly significant in the development of various therapeutics and diagnostics. In the present study, we report the one-pot and rapid synthesis of silver nanoparticles (AgNPs) by quercetin, a flavonoid found in various edible plants. The nanoparticles were then characterized using UV-VIS spectrophotometry, Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The role of quercetin in the synthesis of silver nanoparticles was demonstrated. The nanomaterial was 20–30 nm in size and spherical in shape. The silver nanoparticles were also confirmed to show antioxidant activity at 80 μg/ml concentration in vitro by DPPH, FRAP, and power reduction methods.

Opis:
An eco-friendly and efficient one-pot synthesis of penta-substituted pyrrole derivatives via a four-component reaction of maldrum’s acid, arylglyoxal monohydrate, dimethyl but-2-yne-dioate and amines under catalyst-free conditions in an environmentally friendly medium is described. The simple experimental procedure, catalyst-free reaction conditions, short period of conversion, and excellent yields are the advantages of the present method. Good chemical yields have been achieved without the need for chromatography and recrystallization or other purification methods.

Opis:
A Series of tetrahydropyrimidine has been derived by LaCl3•7H2O catalysed one pot three component biginelli reaction. The compounds have synthesised from an aldehyde, ethyl acetoacetate and urea or thiourea in an ethanolic medium using a catalytic amount of (LaCl3•7H2O). This method provides quantitative yield and the catalysis can be easily recovered from the reaction medium and be re-used.

Opis:
A green resourceful, eco-friendly and facile protocol was developed for the synthesis of benzylamine coumarin derivatives by the reaction of 4-hydroxy coumarin, secondary amine and aromatic aldehyde in the presence of PEG400 as a solvent as well as catalyst at room temperature. A wide range of functional groups were tolerated in the developed protocol. The structures of all the synthesized compounds were confirmed by 1H NMR, IR, MASS and Elemental Analysis. The target molecules were obtained in good to excellent yield applying this method.
