The desired products were simply prepared from different aldehydes, β-dicarbonyls and ammonium acetate in the presence of a low loading of chitosan supported copper(II) sulfate (CSCS) in EtOH under reflux conditions. The biodegradable CSCS catalyst was characterized by field emission scanning electron microscopy (FESEM) and energy-dispersive X-ray spectroscopy analysis (EDX) methods as well as coupled plasma-atomic emission (ICP-AE) and FT-IR spectroscopy. The CSCS catalyst is recyclable and reused four times without significant loss of its activity.

Research paper thumbnail of Sodium alginate: An efficient biopolymeric catalyst for green synthesis of 2-amino-4H-pyran derivatives

International Journal of Biological Macromolecules, 2016

Corresponding 4H-pyran derivatives were obtained in high to excellent yields after 25-150min stirring in 2mL EtOH under reflux conditions in the presence of 10mol% of sodium alginate, equimolar amounts of aldehydes, malononitrile and 1,3-dicarbonyl compounds. The catalyst was easily separated from the reaction mixture to obtain desired products in excellent purity as shown by FTIR and (1)H NMR spectroscopic methods. Avoiding the use of any transition metal, one-pot and multi-component procedure catalyzed by a renewable biopolymer, the reusability of the catalyst, broad substrate scope and operational simplicity are important features of this methodology for preparation of medicinally important compounds.

Research paper thumbnail of Molecular determination of glutaric aciduria type I in individuals from southwest iran

The disease is resulted from mutational inactivation in the GCDH gene encoding the glutaryl-CoA dehydrogenase. The defective enzyme causes the accumulation of an excessive level of intermediate breakdown products that leads to the brain damage. In spite of the clinical features, diagnosis of GAI has been often confusing, because of variability in the clinical manifestations of patients. Early diagnosis and treatment can though prevent irreversible disease progression and consequent brain damage; otherwise the affected individuals will die in their first decade of lives.
