[ 1 ] - Diethylenetriamine supported on cellulose as a biodegradable and recyclable basic heterogeneous catalyst for the synthesis of spirooxindole derivatives
In the present study, the synthesis of diethylene triamine supported on cellulose biopolymer as a biodegradable solid basic heterogeneous catalyst was suggested. Then, the applicability of the synthesized catalyst cellulose bonded N-propyl diethylene triamine (CBPDETA) was tested for the synthesis of oxindole derivatives, an important class of potentially bioactive compounds. A various series o...
[ 2 ] - Essential oil composition of Cleome heratensis (Capparaceae) at different growing stages
In this study, the essential oil content in the aerial parts of Cleome heratensis which is growing in the east of Iran was investigated. The aerial parts of the plant were collected from the late August to October 2014, for a total of four harvests (S1-S4). Essential oils were isolated by hydro-distillation. The oils were analyzed by GC-FID and 30 constituents, representing 84.93-92.9 % of the ...
[ 3 ] - Mn(II) salen complex immobilized on nano silicagel as a recyclable heterogeneous catalyst for oxidation of alcohols to their corresponding carbonyl compounds
Mn(II) salen complex immobilized on nano silicagel was prepared by incorporating Mn(II) salen complex into a nanosilica matrix and characterized by TGA, XRD, atomic absorption spectroscopy and was successfully applied as catalyst for the oxidation of alcohols. Oxidation of a series of alcohols in acetonitrile over immobilized Mn(II) salen complex using tetrabutylammonium peroxymonosulfate (TBAO...
[ 4 ] - Efficient procedure for the synthesis of quinoline derivatives by NbCl5.PEG and NbCl5 in glycerol as green solvent
Quinolines, an important class of potentially bioactive compounds, have been synthesized by treatment of O-aminoarylketones and carbonyl compounds utilizing niobium (V) chloride / polyethylenglycole(NbCl5.PEG) and niobium(V)chloride (NbCl5) as available and inexpensive catalysts. The quinoline derivatives were prepared in glycerol, an excellent solvent in terms of environmental impact, with hig...
[ 5 ] - The comparison of the antioxidant capacity of methanol extract in three species of Artemisia (A. sieberi Besser, A. aucheri, and A. deserti Krasch)
Artemisia deserti Krasch (A. deserti), Artemisia aucheri (A. aucheri) and Artemisia sieberi Besser (A. sieberi) are three members of Asteraceae (compositae) family, which grow widely in the even and high areas of Birjand, Iran. This study has attempted to compare the total antioxidant capacity of methanol extracts of these three plants using DPPH (1,1-Diphenyl-2-Picrylhydrazyl) radical scavengi...
[ 6 ] - Microwave assisted green synthesis of α, ά- bis (substituted- benzylidene) alkanones
Microwave assisted green synthesis of α, ά- bis (substituted- benzylidene) alkanones by the crossed- aldol condensation reaction of substituted aryl aldehydes with ketones in the presence of catalytic amount of NbCl5 in good to excellent yields. This reaction is carried out under solvent-free conditions. The results showed that aldehydes bearing electron–donating substituent's on phenyl-ring fa...
[ 7 ] - Phytochemical Screening and Green Biosynthesis of Silver Nanoparticles Using Unripe Fruit of Ziziphus Vulgaris
In this present study, an environmentally friendly and rapid method for the synthesis of silver nanoparticles (SNPs) has been reported using Ziziphus Vulgaris (ZV) unripe fruit extract under mild conditions. The synthesized silver nanoparticles have been characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), fourier transform infrared spectroscopy (FT-IR) and ultravio...
