Abstract
Synthesizing high-density fuels from non-food biomass is of great interest in the field of biomass conversion because they can increase the loading capability and travel distance of vehicles and aircraft as compared to conventional low-density biofuels (<0.78 g/cm3). In this work, we reported a new and facile strategy for the synthesis of high-density biofuels with polycyclic structures from lignocellulose-derived 5,5-dimethyl-1,3-cyclohexanedione and different aldehyde derivatives in two steps under mild reaction conditions, including a developed tandem reaction and a hydrodeoxygenation reaction. Theoretical approaches were used to estimate the fuel properties, which indicate that the obtained biofuels have a high density of 0.78-0.88 g/cm3 and high net heat of combustion (NHOC) values of 44.0-46.0 MJ/kg. A representative biofuel 3c was measured to have a high NHOC of 43.4 MJ/kg, which matched well with the calculated NHOC value of 44.4 MJ/kg, indicating the high accuracy of the theoretical approaches. This work is expected to provide a green strategy for the synthesis of polycyclic high-density biofuels with platform chemicals.

Abstract
In the present work, an innovative biocompatible heterogeneous organo-nanocatalyst is prepared based on the grafting of arginine amino acid on the channels and pores of dendritic fibrous nano silica (DFNS). The designed organo-nanocatalyst (KCC-1-nPr-NH-Arg) was characterized by using Field emission scanning electron microscopy (FE-SEM), Fourier transform infrared spectroscopy (FT-IR), energy dispersive X-ray spectroscopy (EDS), map analysis, and adsorption/desorption (BET-BJH) instruments. The results of analysis shown that the engineered catalyst has uniform fibrous spheres and dendritic structure with high surface area (178 m2 /g) and great pore volume (0.35 cm3 .g-1 ). Because of exceptional dendritic structure of the engineered organo-nanocatalyst, the active sites are available and the dispersion and adsorption capacity of the reagents and products increase in the pores and channels of the catalyst. Hence, KCC-1-nPr-NH-Arg was used as an capable heterogeneous basic nanocatalyst in the synthesis of 1,8-dioxo decahydroacridine derivatives from the one-pot four component reactions of aromatic aldehydes, dimedone, and ammonium acetate in solvent free conditions with shorter reaction times (13-35 min) and higher yields (94-98%) in evaluation with other reported works. It is expected that, the engineered green organo-nanocatalyst can be used to synthesize other organic compounds. This article is protected by copyright. All rights reserved.

Abstract
Organopromoter, 2-aminoethanesulfonic acid was used to catalyze the synthesis of a series of structurally intriguing new hybrids thiazolyl acridine-1,8(2H,5H)-diones and dihydropyrido[2,3-d : 6,5-d']dipyrimidine-2,4,6,8(1H,3H,5H,7H)-tetraones for the first time. 2-Aminoethanesulfonic acid is a biobased organopromoter, used to generate four new bonds for the synthesis of new coupled thiazole-based decahydroacridine-1,8-diones. Superior green credentials, operational simplicity, easy work-up and recyclability of the catalyst are the key strengths of this method. The broad substrate scope, mild reaction conditions, short reaction time, cost effectiveness, high atom economy and good to excellent yields make the present method a distinct improvement over existing methods. Spectral (IR, 1 H-NMR,13 C-NMR, Mass) data and elemental analyses confirmed the structures of the titled products. A series of thiazolyl acridine-1,8(2H,5H)-diones and dihydropyrido[2,3-d : 6,5-d']dipyrimidine-2,4,6,8(1H,3H,5H,7H)-tetraones were screened for their antimicrobial activity against four bacterial and three fungal strains.

Curr Org Synth 2020; 16:939-947.

Abstract
AIM AND OBJECTIVE Nowadays, bisdimedones and 1,8-dioxo-octahydroxanthenes are considered as biologically active materials. Due to this, the synthesis of the mentioned materials is the subject of more interest. Although most of the reported methods have their own merits, however, they generally require the use of expensive reagents, hazardous organic solvents, a tedious workup procedure and reduced recyclability of the applied catalyst system. Overcoming of the above mentioned drawbacks, therefore, encouraged us to investigate the capability of nanostructured NiFe2O4@Cu towards the synthesis of bisdimedones and 1,8- dioxo-octahydroxanthenes under green reaction conditions. MATERIALS AND METHODS Nanoparticles of NiFe2O4@Cu were prepared via a two-step procedure including the preparation of NiFe2O4 by solid-state grinding of Ni(OAc)2·4H2O and Fe(NO3)3·9H2O in the presence of NaOH followed by the immobilization of Cu(0) on the surface of NiFe2O4 nucleus via hydrazine hydrate reduction of Cu(NO3)2·3H2O. RESULTS After the synthesis of NiFe2O4@Cu, the catalytic activity of the Cu-nanocatalyst towards Knoevenagel reaction of aromatic aldehydes with dimedone under different reaction conditions was investigated. The examinations showed that using the molar equivalents of aromatic aldehydes (1 mmol) and dimedone (2 mmol) in the presence of 0.15 g NiFe2O4@Cu under solvent-free conditions chemoselectively afforded structurally different bisdimedone products at 60°C and 1,8-dioxo-octahydroxanthenes at 120°C. CONCLUSION In this study, magnetically, nanoparticles of NiFe2O4@Cu were prepared and then characterized using different analyses. The catalytic activity of the prepared Cu-nanocatalyst was also studied towards solvent-free Knoevenagel condensation of aromatic aldehydes with dimedone. All the reactions were carried out within 15-240 min to afford bisdimedone and 1,8-dioxo-octahydroxanthene products in high yields.

Abstract
Background:
Synthesis of acridinedione derivatives via one-pot multi-component approaches
using highly active and reusable Pd/AlO(OH) heterogenous catalyst was studied. This process
provided a convenient method to obtain various acridinediones with potential biological activities.
The reactions were performed in mild conditions such as low temperature and short reaction
time with desirable yields.
Methods:
Commercially available Pd/AlO(OH) nanoparticles characterized by XRD and SEM methods
were afforded for the synthesis of acridinedione derivatives with high yields. Crude products
were analyzed by GC and 1H NMR. The reactions were completed within 1h at 40°C by the assistance
of ultrasound system.
Results:
Optimization of reaction conditions is of critical case for successful synthesis. Solvent, temperature,
time and amount of catalyst were studied. At the end of the experiments, the synthesis of 1
mmol of acridinedione was optimized by using 25 mg of Pd/AlO(OH) NPs, 3 ml of DMF for 60 min
at 40°C in the ultrasound system. An experimental work to check the reusability of the catalyst was
also studied. Pd/Al(O)OH catalyst in the first run was higher than that of the reused catalyst in the
fifth run. ICP-OES analyses showed palladium leaching into the reaction medium was only 1.1%
which is negligible. Nanocatalyst employed a high activity and good reusability.
Conclusion:
A convenient and versatile method was developed for the synthesis of acridinediones in
a mild condition with absolute conversion and high yield using ultrasound system in the presence of
nanocatalyst.

Abstract
The mechanism of acetic acid (AA), trifluoroacetic acid (TFA), and trichloroacetic acid (TCA) catalyzed three-component cyclocondensation reaction to (4S,6S)-4,6-diphenyl-1,3,5-triazinane-2-thione was determined via density functional calculations. Based on the potential energy surface diagram, TCA was found to be a reasonable catalyst [energy span (δG) is 2 kcal mol-1 less than TFA and AA] for the reaction. An energetic span model implies that TFA and AA show the same catalytic performance. The impact of the presence of halogen atoms in TFA and TCA catalysts is quantified via energy barriers.

Abstract
In this study, the immobilization of copper-layered nickel ferrite on the surface and in the cavities of acid-activated montmorillonite (H+-Mont) was investigated. In this context, magnetic nanoparticles (MNPs) of NiFe2O4 as the prime magnetic cores were prepared. Next, through the reduction of Cu2+ ions with sodium borohydride, the nanoparticles of Cu0 were immobilized on the nanocore-surface of NiFe2O4, and the constituent NiFe2O4@Cu MNPs were obtained. Moreover, through the activation of montmorillonite K10 (Mont K10) with HCl (4 M) under controlled conditions, the H+-Mont constituent was prepared. The nanostructured NiFe2O4@Cu was then intercalated within the interlayers and on the external surface of the H+-Mont constituent to afford the novel magnetic nanocomposite (NiFe2O4@Cu)(H+-Mont). The prepared clay nanocomposite was characterized using FTIR spectroscopy, SEM, EDX, XRD, VSM and BET analyses. The obtained results showed that through acid-activation, the stacked-sheet structure of Mont K10 was exfoliated to tiny segments, leading to a significant increase in the surface area and total pore volume of the H+-Mont constituent as compared to those of montmorillonite alone. SEM analysis also exhibited that the dispersion of NiFe2O4@Cu MNPs in the interlayers and on the external surface of acid-activated montmorillonite was carried out successfully, and the nanoparticle sizes were distributed in the range of 15–25 nm. The BET surface analysis also indicated that through the immobilization of NiFe2O4@Cu MNPs, the surface area and total pore volume of the H+-Mont system were decreased. The catalytic activity of (NiFe2O4@Cu)(H+-Mont) was further studied towards the synthesis of substituted 13-aryl-5H-dibenzo[b,i]xanthene-5,7,12,14(13H) tetraones 3(a–k) and 3,3,6,6-tetramethyl-9-aryl-3,4,5,6,7,9-hexahydro-1H-xanthene-1,8(2H) diones 5(a–k)via the pseudo-one-pot three-component cyclocondensation of 2-hydroxy-1,4-naphthoquinone (Lawsone)/dimedone and aromatic aldehydes in a mixture of H2O–EtOH (1 : 1 mL) as a green solvent at 80–90 °C. The (NiFe2O4@Cu)(H+-Mont) MNPs can be easily separated from the reaction mixture by an external magnetic field and reused for seven consecutive cycles without significant loss of catalytic activity. In this study, the catalytic activity of the prepared (NiFe2O4@Cu)(H+-Mont) MNPs was studied towards the synthesis of dibenzo[b,i]xanthene tetraones 3(a–k) and hexahydroxanthene diones 5(a–k).![]()
