Xanthenes are an important class of heterocycles in medicinal chemistry due to their diverse pharmacological properties. These tricyclic aromatic compounds, characterised by a dibenzo[b,e]pyran core with oxygen atom at central position, have gained significant attention for extensive applications. Beyond pharmaceuticals, xanthenes widely used textiles, food industries, electro-optical devices, dyes, and bioimaging agents. Xanthene derivatives, particularly 9-substituted xanthenes, exhibit wide range biological activities, including antiparasitic, antibacterial, antileishmanial, cytotoxic, neuroprotective, photophysical effects, making them valuable drug discovery. The xanthene scaffold is present various bioactive natural compounds such as mulgravanols A B, hermannol, (+)-myrtucommulone D, homapanicones blumeaxanthene II, acrotrione. Clinically relevant xanthene-based drugs include propantheline bromide (antimuscarinic), methantheline (antispasmodic), phloxine B (photosensitiser antimicrobial therapy). Thus, synthetic approaches been developed the construction ultrasound-assisted green methodologies gaining prominence. Ultrasound technique offers advantages over conventional methods, higher yields, faster reaction rates, improved selectivity under milder conditions. This review comprehensively explores synthesis functionalised derivatives eco-friendly alternative. To best our knowledge, this first in-depth focusing on methodology ultrasound irradiation.

A family of sustainable carbon catalysts with different chemical surface, active and selective for the synthesis benzodiazepine 1 (BDZ), from o-phenylendiamine (OPD) 2 acetone 3, under mild conditions, is reported. Catalysts were prepared by acids treatments H2SO4 or H3PO4 an activated doped ZnO at 3% wt (N3Zn) and, subsequently, submitted to additional thermal treatment in air. Simultaneously leaching, surface C-SO3 groups generated N3Zn (N3Zn-S) whereas led C-PO3 functions (N3Zn-P sample). The partially removes (N3Zn-S-C sample) while oxidized C-OPO3 (N3Zn-P-C). Our results suggest that these modifications are key on catalytic performance, pointed out importance nature distribution acid sites surface. Remarkably, investigated (N3Zn-S samples) more than NS catalyst obtained direct AC H2SO4, this last mainly functionalized C-OSO3 groups. Although resulting showed both a similar activity, some differences selectivity BDZ observed, attributed certain specificity P-functions depending strength reaction conditions. These supported DFT calculations.

Abstract We synthesized CNTs-Fe3O4-IL, which are multi-walled carbon nanotubes modified with an imidazolium-ionic liquid. Then, we conducted a comprehensive analysis of the structure, morphology, and properties nanocomposites using various characterization techniques. These techniques included VSM, FT-IR, TEM, TGA, DTA, SEM, XRD. In this manuscript, novel efficient microwave-assisted multicomponent synthesis method for spiroindoline-3,4'-pyrazolo[3,4-b]quinoline-2,5'(6'H)-diones ionic liquid-coated magnetic as catalyst is presented. The involves condensation 3-methyl-1H-pyrazole-5-amins, cyclohexane-1,3-diones, isatin derivatives under microwave irradiation in presence nanotubes. Ionic-liquid-coated serve synthesis, providing improved efficiency separation ability. was also tested reuse retained almost all its activity after several cycles, proving that highly sustainable. This study proves approach effective environmentally friendly obtaining spirocondensed heterocyclic compounds. new will allow rapid biologically active compounds potential applications drug discovery materials science.
