Heterocycles constitute the integral part of the most of United States food and drug
administration (USFDA) approved drugs. Over the past decade, ionic liquids have emerged …

The nitrogen-bridgehead is a common structural motif present in a multitude of natural
products. As many of these abundant compounds exhibit biological activities, eg against …

We report a simple, clean, and straightforward method for the non-covalent immobilization of
protic acidic ionic liquids on nano silica sulfuric acid. Initially, two organic zwitterions were …

In this study, phosphotungstic acid (H3PW12O40)-supported melamine–terephthalaldehyde
Covalent Organic Framework (COF-PTA) has been prepared as a novel solid acid catalyst …

In this research work, a novel strategy for the heterogenization of sultone based acidic ionic
liquids via their non-covalent immobilization on nano silica sulfuric acid is reported and the …

Herin, a new nanohybrid acid catalyst was fabricated for the efficient biodiesel production. At
the first, magnetic porous nanosheets of graphitic carbon nitride (gC 3 N 4@ Fe 3 O 4) was …

In this research, the synthesis of novel indeno [1, 2-b] pyrano [2, 3-f] chromene-2, 12 (13H)-
dione derivatives in the presence of a newly introduced magnetically recoverable nanosolid …

Improvements in Sustainable Organic Synthesis are usually related to the investigation of
less hazardous, non-corrosive and renewable materials, as well as waste prevention …

A novel caffeine-based acidic ionic liquid was synthesized, characterized, and utilized as an
efficient and green catalyst for synthesizing DHPMs, xanthenediones, and acridinediones …

The synthesis of 2 H-indazolo [2, 1-b] phthalazine-triones and triazolo [1, 2-a] indazole-
triones catalyzed by 1 H-1, 2, 4-triazole-3-thiol-functionalized core–shell Fe3O4@ SiO2 …
