Abstract
The study aimed to develop an efficient catalyst, biochar/Fe3O4@SiO2-Ag magnetic nanocomposite, to synthesize bioactive benzylpyrazolyl coumarin derivatives through a one-pot multicomponent reaction. The catalyst was prepared using Ag nanoparticles synthesized with Lawsonia inermis leaf extract and carbon-based biochar obtained through pyrolysis of Eucalyptus globulus bark. The nanocomposite contained a silica-based interlayer, highly dispersed Ag nanoparticles, and a central magnetite core, which responded well to external fields. The biochar/Fe3O4@SiO2-Ag nanocomposite showed excellent catalytic activity and could be easily recovered using an external magnet and reused five times without significant loss of performance. The resulting products were tested for antimicrobial activity and showed significant activity against various microorganisms.

Abstract
Herein, the synthesis of graphitic carbon nitride (g-C3N4) via the simple heating of cheap and readily available urea as the starting material has been reported. The catalytic activity of the prepared g-C3N4 was investigated for the synthesis of chromeno[2,3-b]pyridine and benzylpyrazolyl coumarin derivatives in an ethanol medium. The reactions were performed under mild conditions to achieve widely functionalized target products in a one-pot operation. The as-synthesized g-C3N4, being a heterogeneous catalyst, demonstrates excellent recyclability up to the 5th consecutive run without a significant decrease in its catalytic activity and yield of the product. A gram-scale reaction was performed to demonstrate the industrial applications of the present protocol. The green chemistry metrics such as environmental factor (E-factor), atom economy (AE), carbon efficiency (CE), and reaction mass efficiency (RME) were calculated and found to be very close to the ideal values. Additionally, operation simplicity, wide substrate scope, easy reusability of the catalyst, and avoidance of metal contamination in the products drive the process toward green and sustainable development.

Abstract
A series of pyrano[3,2-c]quinolone derivatives has been synthesized in the presence of taurine (2-aminoethanesulfonic acid) as a green bio-organic catalyst and water as the solvent. The target compounds were synthesized through the three-component reaction between aldehydes, malononitrile/ethylcyanoacetate, and 4-hydroxy-1-methyl-2(1H)-quinolone. The advantages of this protocol are excellent yields of products, short reaction times, cost efficiency, atom economy, and a simple work-up procedure with no need for extra purification techniques. Moreover, the catalyst can be easily recovered and reused for up to three cycles without losing any significant activity.

Abstract
:
Organocatalysis has become a powerful tool in organic synthesis for the formation of C-C and C-X (N, S, O, etc.) bonds, leading to the formation of complex molecules from easily available starting materials. It provides an alternative platform to the conventional synthesis and fulfills the principles of green chemistry. During the last decades, taurine has emerged as a promising organocatalyst in an array of organic transformations in addition to its plentiful biological properties. It is highly stable, easy to store and separate, water-soluble, of low cost, easily available, and recyclable. The present article highlights the recent and up-to-date applications of taurine in organic transformations.

Abstract
Nitrogen, oxygen and sulfur-containing fused heterocycles are of great importance
because of their exciting and diverse biological activities. The construction of the carbonnitrogen
and carbon-oxygen through a multicomponent reaction approach by using ecofriendly
reusable heterogeneous catalysts are of significant importance as it opens avenues for
the introduction of nitrogen and oxygen in organic molecules. Thus, green methodologies
have gained particular significance in this field; today, green chemistry is considered a tool
for introducing sustainable concepts at the fundamental level. This review emphasizes and
discusses the current progress on the applications of eco-friendly, recyclable heterogeneous
catalysts for the synthesis of different heterocyclic fused systems and their green protocols.
We paid particular attention to the specific integration of carbon-nitrogen, and carbon-oxygen
bond-forming fused heterocycles by a one-pot approach by evaluating the literature between 2012 and the middle of
2020. The efficiency of the catalyst is assessed in terms of reaction time, yield and possible reusability. The MCR and
heterogeneous catalyst strategies have demonstrated broader scope, economical and viability for the green and sustainable
processes in the field of synthetic organic chemistry.

Abstract
The focus of the current study was to develop a functional and bioactive scaffold through the combination of 3D polylactic acid (PLA)/polycaprolactone (PCL) with gelatin nanofibers (GNFs) and Taurine (Tau) for bone defect regeneration. GNFs were fabricated via electrospinning dispersed in PLA/PCL polymer solution, Tau with different concentrations was added, and the polymer solution converted into a 3D and porous scaffold via the thermally-induced phase separation technique. The characterization results showed that the scaffolds have interconnected pores with the porosity of up to 90%. Moreover, Tau increased the wettability and weight loss rate, while compromised the compressive strengths. The scaffolds were hemo- and cytocompatible and supported cell viability and proliferation. The in vivo studies showed that the defects treated with scaffolds filled with new bone. The computed tomography (CT) imaging and histopathological observation revealed that the PLA/PCL/Gel/Tau 10% provided the highest new bone formation, angiogenesis, and woven bone among the treatment groups. Our finding illustrated that the fabricated scaffold was able to regenerate bone within the defect and can be considered as the effective scaffold for bone tissue engineering application.
