1 - Brönsted acidic ionic liquid as a recyclable catalyst for the one pot four-component synthesis of substituted pyrano[2,3-c]pyrazolesIranian Journal of Catalysis , العدد 1 , السنة 6 , زمستان 2016An efficient, mild and environmentally friendly method was reported for the synthesis of An efficient, mild and environmentally friendly method was reported for the synthesis of pyranopyroles from aryl aldehydes, ethyl acetoacetate, malononitrile and hydrazine hydrate i أکثرAn efficient, mild and environmentally friendly method was reported for the synthesis of An efficient, mild and environmentally friendly method was reported for the synthesis of pyranopyroles from aryl aldehydes, ethyl acetoacetate, malononitrile and hydrazine hydrate in the presence of catalytic amounts of Methyl imidazolium hydrogen sulfate ([Hmim][HSO4]) as an efficient catalyst. These syntheses were performed via a one-pot four-component condensation in water/ethanol (50%) at 50 ◦C. This method easily provides the coresponding products in good yield and relatively short reaction times. Also the reusability of the catalyst was investigated, the catalyst could be employed four times, although its activity gradually decreased. تفاصيل المقالة -

2 - Synthesis and in vitro antibacterial study of dihydropyrano[3,2-c]chromene derivatives by nano fluoro apatite doped with Mg and Si as a cooperative catalystIranian Journal of Catalysis , العدد 1 , السنة 10 , زمستان 2020One of the important Multi-component reaction (MCRs) is the synthesis of dihydropyrano chromene derivatives by one-pot reaction. In this research, an inexpensive and effective one pot three component procedure with good yields for the synthesis of dihydro pyrano chromen أکثرOne of the important Multi-component reaction (MCRs) is the synthesis of dihydropyrano chromene derivatives by one-pot reaction. In this research, an inexpensive and effective one pot three component procedure with good yields for the synthesis of dihydro pyrano chromenes is reported. In this method, the synthesis of pyrano chromene derivatives was followed by using 4-hydroxycoumarin, malononitrile and aldehydes in the presence of catalytic amount of nano fluoro apatite doped with Mg and Si (Mg-Si-FA). It should be cited that all reactions were carried out in H2O/EtOH as the solvent under reflux condition and the corresponding products were obtained in good yields and pretty short reaction time. Moreover, the anti-bacterial properties of the present products were studied by determination of their minimum inhibitory concentration (MIC). تفاصيل المقالة -
