Facile One‐pot Synthesis of Arylsulfonyl‐4H‐pyrans Catalyzed by Ru Loaded Fluorapatite

“…In our continuous efforts to develop swift and green methodologies for the generation of novel heterocyclic molecules, earlier we have reported various highly efficient methods for synthesis of different condensed heterocyclic frameworks . We have also evaluated the biological activity of few series .…”

Ag2O on ZrO2 as a Recyclable Catalyst for Multicomponent Synthesis of Indenopyrimidine Derivatives

“…We recently reported several green synthetic approaches of various medicinally interesting heterocyclic scaffolds [ 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 ]. Encouraged by those favorable results with different substituted heterocyclic scaffolds, here we describe the synthesis and characterization of silver loaded on zirconia and its efficiency in the one-pot synthesis of functionalized indenopyrimidines via a three-component reaction at room temperature (RT).…”

Innovative Efficient Method for the Synthesis of 1,4-Dihydropyridines Using Y2O3 Loaded on ZrO2 as Catalyst

“…We are encouraged by promising results in evolving synthetic methodologies for various heterocyclic molecules. − Recently, we have designated various procedures for the synthesis of various biologically interesting heterocyclic protocols. − In this communication, in continuation of the pursuit for development of efficient catalyst materials, we report a heterogeneous catalyst, yttrium loaded on zirconia (Y 2 O 3 /ZrO 2 ), and its characterization. In addition, we examined its activity for the synthesis of a series of novel functionalized 1,4-dihydropyridine derivatives using a one-pot four-component reaction at room temperature with ethanol as solvent.…”
