Cerium Chloride (CeCl3·7H2O) as a highly efficient catalyst for one-pot Three-Component Mannich reaction
Kidwai, Mazaahir;Anwar, Jahan;
Journal of the Brazilian Chemical Society , 2010, DOI: 10.1590/S0103-50532010001200002
Abstract: we have demonstrated the use of cecl3· 7h2o as highly efficient catalyst for one-pot mannich reaction to afford β-amino carbonyl compounds in good to excellent yield within shorter period of reaction time. the process is mild, efficient, environmentally benign with the use of little amount of catalyst.

Abstract: For Muslims, Islam is time conscious and eternal, its wisdom and rules having emanated from High are not only constant but are, simultaneously, responsive to changing circumstances of every environment and culture or civilization. Its philosophies apply to all times and places. The religion establishes the moral guidelines for good behavior at all aspects of life on which legal rules can develop and it also orders humans to regulate their activities in worldly life according to their time, conditions and environmental backgrounds. Contrary to this, some people presume that the passage of time provides adequate ground for the need for new guidance. For them, a religion revealed fourteen centuries ago must have grown unfashionable and unsuitable to satisfy the needs of the new epoch, meet the challenges of scientific knowledge, and augment the excitement of modern civilizations.1 This paper examines the Islamic perspective of time and the all-encompassing nature of its wisdom or knowledge (which is beyond the absolute restriction of time and space) and its approach to the clash of civilizations. The theoretical framework is Huntington’s CoC-theory. It argues that the clash between the Islamic nations and Western powers, for Muslims, is not a struggle for cultural identity as the theory postulated, but as a result of the desire of the West to obstruct the establishment of values based on Islamic religious wisdom which is dearer to the Islamic nations than the West estimates.
Clinical Profile and Treatment Management of Heart Failure with Preserved Systolic Function in Rural Setting of India  [PDF]

Background: In recent decades, the hospital admission due to heart failure with normal ejection fraction (HFnEF) or diastolic heart failure has increased particularly in elderly patients. However, sufficient data regarding prevalence, etiologies and treatment of diastolic heart failure are not available for Indian population. So, we carried out an observational study to determine clinical profile and medical therapy for patients experiencing diastolic heart failure. Methods: This was prospective observational study carried out in rural area of India for the period of 12 months. All the patients diagnosed with heart failure with normal ejection fraction were included in the study. If the patient was having severe anemia (hemoglobin < 8.00 g/dl), hemodynamically significant valvular disease, prosthetic valve replacement, and ventricular pacemaker, they were excluded. Results: A total of 53 patients diagnosed with HFnEF were included in the study. There were 24 male patients. Hypertension, CAD and diabetes mellitus were present in 33, 24 and 16 patients respectively. 18 patients developed severe diastolic dysfunction and more common in female as compared to male (37.9% vs. 33.3%). Most frequently observed clinical feature was tachycardia (96% cases) followed by pedal edema (86%). The patients were treated according to underlying cause. Conclusions: Diastolic heart failure is more common in elderly patients. In Indian population, diastolic heart failure has been associated with hypertension, diabetes mellitus and coronary artery diseases in most of the

An expeditious synthesis of 3,4-dihydrobenzo[2,3-d]pyrimidines using inorganic solid supports
Journal of the Serbian Chemical Society , 2004,
Abstract: A series of novel 5-substituted-8-cyano-4,6,7-triphenyl-3,4-dihydrobenzo [2,3-d]pyrimidines were synthesized by the condensation of 6-substituted-2-amino-1-benzoyl-3-cyano-5-hydroxy-4,5-diphenyl-1,3-cyclohexadiene and formamide, using inorganic solid supports under microwaves. Some of the compounds were found to be effective against some fungal and bacterial strains.

Conceptual Analysis and Fieldwork in Macroeconometric Methodology: Modeling Unemployment, Inflation and Production  [PDF]
Karim Errouaki
Technology and Investment (TI) , 2014, DOI: 10.4236/ti.2014.53015

The recent failure of commonly accepted, inductive, econometric models to provide insights into real, macroeconomic phenomenon during economic crises has provoked a debate concerning contemporary econometric methodology. Based on the foundations laid by Haavelmo, and Hollis and Nell, an assessment of Edward J. Nell’s (1998) “unifying methodological framework” (UMF) is offered. Nell’s UMF places socioeconomic institutions and interdependencies, and technological realities as basis of analysis. Using “conceptual analysis” and “fieldwork” Nell presents an alternative to generally accepted, mainstream, econometric methodology. The purpose of this paper is to look at some examples of the way, and this can help develop useful theory and improve macroeconometric model building. Applying Nell’s UMF to unemployment, inflation, and production reveals a methodological advance that promises more realistic insights into macroeconomic phenomena than is offered by contemporary, mainstream, econometric models.

Efficient CAN catalyzed synthesis of 1H-indazolo[1,2-b] phthalazine-1,6,11-triones: An eco-friendly protocol
Kidwai Mazaahir,Chauhan Ritika,Jahan Anwar
Chinese Science Bulletin , 2012, DOI: 10.1007/s11434-012-5081-7
Abstract: A convenient, economical and green approach to the synthesis of 1H-indazolo[1,2-b]phthalazine-1,6,11-trione derivatives has been achieved via a one-pot protocol using phthalhydrazide, a cyclic-β-diketone and an aldehyde in the presence of a ceric ammonium nitrate catalyst in polyethylene glycol. The simple work up, mild conditions, excellent yields, inexpensive and non-toxic catalyst and simple solvent recyclability render this protocol both attractive and economically viable.
C-Arylation reactions catalyzed by CuO-nanoparticles under ligand free conditions
Mazaahir Kidwai,Saurav Bhardwaj,Roona Poddar
Beilstein Journal of Organic Chemistry , 2010, DOI: 10.3762/bjoc.6.35
Abstract: CuO-nanoparticles were found to be an excellent heterogeneous catalyst for C-arylation of active methylene compounds using various aryl halides. The products were obtained in good to excellent yield. The catalyst can be recovered and reused for four cycles with almost no loss in activity.
N-acylation of ethanolamine using lipase: a chemoselective catalyst
Mazaahir Kidwai,Roona Poddar,Poonam Mothsra
Beilstein Journal of Organic Chemistry , 2009, DOI: 10.3762/bjoc.5.10
Abstract: The N-acylation of ethanolamine (2) with various fatty acids 1a–d and esters of fatty acids 1e–h using Candida antarctica B lipase (Novozym 435) are described and optimum conditions for selective N-acylation rather than O-acylation are also discussed. Microwave assisted solution phase, solid supported and conventional methods were investigated and results were compared. There is a synergy between the enzyme catalysis and microwave irradiation.
