In this research, a new flower-like Ni0.77/Co0.23– benzene–1,3,5–tricarboxylate (BTC) bimetallic organic framework (Ni/Co–BTC BMOF) is synthesized via the cathodic electrosynthesis (CE) method, based on nickel and cobalt metals and BTC linker. The synthesized BMOF is characterized by several methods, including Fourier transform infrared spectroscopy (FT-IR), powder X-ray diffraction (PXRD), field emission scanning electron microscopy (FE-SEM), and energy dispersive X-ray analysis (EDX). The catalytic activity of the resulting Ni/Co is evaluated in a one-pot four-component reaction of dimedone, aromatic aldehyde, 4–hydroxycoumarin, and ammonium acetate for the synthesis of chromeno[4,3–b]quinolone derivatives under solvent-free condition. The Ni/Co–BTC BMOF catalyst showed very good activity in the tested reaction, and a wide scope of starting materials gave the desired products in high isolated yields in the presence of the Ni/Co–BTC BMOF catalyst. The recovery of Ni/Co BMOF was achieved by a centrifuge, and it was reused at least six times without any significant decrease in catalytic activity.

We report an ecofriendly synthetic approach for the fabrication of biogenic gold nanoparticles (AuNPs) using electron-rich sea cucumber extract as a bio-reductant and stabilizing agent in reducing gold cations into AuNPs at the optimal conditions. The produced AuNPs are spherical in shape with an average particle size of 11 ± 1.5 nm in transmission electron microscopy (TEM) and exhibited a crystal structure of face-centered cubic in X-ray diffraction (XRD) analyses. Our results indicated that bioinspired AuNPs demonstrate superior catalytic activity in the safe and facile one-pot synthesis of polyhydroquinoline derivatives under solvent-free reaction conditions. This green route encompasses multiple benefits including highly recyclable bioinspired catalyst (5 cycles), short reaction times, convenient workout, high to excellent product yields (82%–97%), and nonhazardous conditions.

An efficient one-pot, three-component synthesis method of highly functionalized coumarin fused 7,13-dihydro-5-oxa-13-aza-indeno[2,1-b]- phenanthrene and chromeno[4,3-b]quinoline derivatives was accomplished using aromatic aldehyde, 4-aminocoumarin and cyclic 1,3-dione in acetic acid at reflux temperature. Environmental-friendly protocol has advantages of high yields, creating three new bonds and one stereocenter in single operation. Further, XRD and DFT study confirmed the molecular structure, stability and different interaction in the crystal packing.

A simple, convenient, environmentally benign, and mild synthetic method has been established to afford highly decorated indenodihydropyridine and dihydropyridine derivatives employing a green solvent ethyl-l-lactate and an organo-catalyst (±)lactic acid. A wide range of functional groups were tolerated in the developed protocol. The target molecules were obtained in moderate to good yields applying the current method.
