Sonocatalysis in solvent free conditions: An efficient eco-friendly methodology to prepare chalcones using a new type of amino grafted zeolites

Microwave assisted synthesis of some halosubstituted chalcones

“…Chalcones are also synthesized by using microwave irradiation, ultrasound irradiation [16] and by Suzuki reaction [17]. Various modified methods for synthesis of chalcones has been reported using different catalyst such as SOCl 2 [18], natural phosphate / lithium nitrate [19], KF / natural phosphate [20], acyclic acidic ionic liquid [21], Na 2 CO 3 [22], high-temperature water [23], sodium carbonate [24], ZrCl 4 and ionic liquid [25], Table 1. Microwave assisted synthesis of halosubstituted chalcones, 2a-i.…”

V‐N‐C catalysts anchored to mesoporous Al‐SBA‐15 with tailorable pore sizes for the synthesis of spirooxindole dihydroquinazolinones derivatives

“…Moreover, the addition of heteroatoms such as aluminum (with lower than silicon valence) introduces the negative charges in the silica walls that are compensated by protons, and generates an acidity in these systems, improving the surface properties of the final product . Based on these distinctive attributes, a large number of research groups have pursued new and creative approaches toward incorporating multiple functional groups onto heterogeneous catalysts, which can catalyze multistep reaction cascades in one system or work in a cooperative manner to alter the characteristics of a single reaction …”

“…[19] Based on these distinctive attributes, a large number of research groups have pursued new and creative approaches toward incorporating multiple functional groups onto heterogeneous catalysts, which can catalyze multistep reaction cascades in one system or work in a cooperative manner to alter the characteristics of a single reaction. [20][21][22][23][24][25][26][27][28][29] In the current work, the use of material with surface functional groups shows improved selectivity catalyst. Consequently, we synthesize the novel hybrid V-bis(2-aminobenzamide)@Al-SBA-15 (V-N-C@Al-SBA-15) by chloro-functionalized with employing 3chloropropyltriethylsilane (CPTES) and anchored bis(2aminobenzamide) on it.…”

Synthesis and Screening of Human Monoamine Oxidase‐A Inhibitor Effect of New 2‐Pyrazoline and Hydrazone Derivatives

“…They are commonly synthesized via the Claisen–Schmidt condensation between acetophenone and benzaldehyde. Chalcones are important intermediates in the synthesis of many pharmaceuticals including 2‐pyrazolines and hydrazones , and they have important biological activities such as anti‐inflammatory , antibacterial , antiviral , antioxidant , antineoplastic , and MAO inhibitor activities .…”
