we describe here a suitable approach for the synthesis of n-unsubstituted monocyclic b-lactams under mild reaction conditions by the annelation of imines with substituted acetylchlorides. in this method the reaily available phtalimidoacetyl chloride were allowed to react with - dibenzylideneiminotoluene (hydrobenzamide) in the presence of an equimolar amount of triethylamine in refluxing toluen...

Platychaete aucheri is one of the exclusive and important rangeland species in the south of the country that has an important role in animal nutrition. In this study, using a generalized increase model, the pattern of response of this species to the slope of soil and topographic factors in its habitats in the province Hormozgan was identified and for this purpose, three regions of Bastak, Sirma...

abstract in first part of this project, the use of a new and biguanid-like catalyst supported on silica as a recyclable catalyst provides a new route for the synthesis of a variety of arylalkylidene rhodanine derivatives through knoevenagle reaction in at present of solvent at room temperature. rhodanine derivatives and especially arylalkylidene rhodanines have proven to be attractive compound...

in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...

Background: A unique subset of Individuals with normal body mass index (BMI= 18.5-24.9 kg/m2) and high body fat percentage (above 30% in women and 23% in men) that are termed as normal weight obese, are at increased risk for development of the metabolic syndrome and chronic diseases because the adipose mass and the excess of fat mass are an important source of proinflammatory cytokines. The aim...

abstract this paper discusses several commonly used models for strategic marketing¹ including market environmental analysis methods (i.e. swot and pest analysis) and strategic marketing tools and techniques (i.e. boston matrix and shell directional policy matrix)and shows how these models may help a firm to achieve its strategic goals. at first, the main reason for doing this research is de...

  Seed priming is the most important technique for increasing the germination power. This study was conducted to investigate the effects of halopriming and hydropriming on improvement of seed germination in black locust (Robinia pseudoacacia L.) in a completely randomized design with 4 replications. Halopriming treatments of KNO3 with concentrations including (100, 250, 500, 750 mM) and hydropr...
