TL;DR: In this paper, a simple and convenient procedure for the synthesis of aryl-14 H -dibenzo[ a. j ]xanthenes was described through a one-pot condensation of β-naphthol with aryls aldehydes in the presence of sulfamic acid as the catalyst in a solvent-free media using both conventional heating and microwave irradiation.

TL;DR: In this article, the condensation of β-naphthol with aromatic aldehydes in the presence of cellulose sulfuric acid under solvent-free media to afford the corresponding aryl-14H-dibenzo [a.j]xanthenes in excellent yields and short reaction times is described.
Abstract: The condensation of β-naphthol with aromatic aldehydes in the presence of cellulose sulfuric acid under solvent-free media to afford the corresponding aryl-14H-dibenzo [a.j]xanthenes in excellent yields and short reaction times is described. The reaction work-up is very simple and the catalyst can be easily separated from the reaction mixture and reused several times in subsequent reactions.

TL;DR: The pyranochromene analog 7b showed good antitubercular activity and cytotoxicity and was superior to the antituberculosis drug, pyrazinamide (PZA; IC(90): >20μg/mL).
63 citations
TL;DR: In this article, a three component coupling of one pot reaction which servers as the most convenient route to the synthesis of benzopyran derivatives using the TiCl4 catalyst (10 mol %) under solvent free conditions is described.
57 citations
TL;DR: In this paper, a series of (Z)-5-((N-benzyl-1H-indol-3-yl)methylene)imidazolidine-2,4-dione derivatives that incorporate a variety of aromatic substituents in both the indole and N-bitzyl moieties have been synthesized.

TL;DR: In this paper, mixed materials of the metal-organic framework (MOF), chromium(III) terephthalate (MIL-101), and phosphotungstic acid (PTA) were synthesized in aqueous media in the absence of hydrofluoric acid XRD analysis indicates the presence of ordered PTA assemblies residing in both the large cages and small pores of MIL-101, which suggests the formation of previously undocumented structures.
Abstract: Hybrid materials of the metal–organic framework (MOF), chromium(III) terephthalate (MIL-101), and phosphotungstic acid (PTA) were synthesized in aqueous media in the absence of hydrofluoric acid XRD analysis of the MIL101/PTA composites indicates the presence of ordered PTA assemblies residing in both the large cages and small pores of MIL-101, which suggests the formation of previously undocumented structures The MIL101/PTA structure enables a PTA payload 15–2 times higher than previously achieved The catalytic performance of the MIL101/PTA composites was assessed in the Baeyer condensation of benzaldehyde and 2-naphthol, in the three-component condensation of benzaldehyde, 2-naphthol, and acetamide, and in the epoxidation of caryophyllene by hydrogen peroxide The catalytic efficiency was demonstrated by the high (over 80–90%) conversion of the reactants under microwave-assisted heating In four consecutive reaction cycles, the catalyst recovery was in excess of 75%, whereas the product yields were

TL;DR: A comparison of the drug potency of the hybrid molecules with their individual counterparts is discussed for quantifying the significance of the concept of molecular hybridisation.
313 citations
TL;DR: In this article, the general discussion on green chemistry and catalysis; and solid acid catalysts are discussed in the context of a review of the last few years for various synthetic protocols.
254 citations
TL;DR: The 2,1,3-Benzothiadiazole (BTD) is one of the most important nuclei used in the chemistry of photoluminescent compounds and applicable for light technology as discussed by the authors.
