Three-component synthesis of 4H-pyran scaffolds accelerated by a gabapentin-based natural deep eutectic solvent

The development of environmentally benign synthetic protocols has attracted increasing attention in recent organic syntheses. As a part of this concept, our group synthesized a new natural deep eutectic solvent (NADES) by using gabapentin and choline chlo

Novel Pyran and Polyhydroquinoline Derivatives: Inhibiting Human Osteosarcoma Activity

A series of pyran 1–6 and polyhydroquinoline derivatives 7–9 are synthesized targeting anticancer agents for clinical trials. Their structures are characterized by IR, 1H NMR, and HRMS spectra, and single crystal X-ray crystallography. Their anticancer activity against four human osteosarcoma cells (Saos-2, MG-63, 143B, and U2-OS) is evaluated in vitro using the MTT assay. The compounds 7–9 demonstrate high anticancer activity against the four cancer cells.

Synthesis, Single Crystal X-ray Structure Analysis and Computational Electronic Structure Investigations of 2-amino-7,7-dimethyl-4-(4-(methylthio)phenyl)-5-oxo-5,6,7,8-tetrahydro-4H-chromene-3-carbonitrile

A clean, efficient and mild method is presented for one-pot three-component synthesis of 2-amino-7,7-dimethyl-4-(4-(methylthio)phenyl)-5-oxo-5,6,7,8-tetrahydro-4H-chromene-3-carbonitrile using nickel ferrite magnetic nanoparticles as a recyclable catalyst in green solvent at 40?°C.

One-pot synthesis of substituted 4H-chromenes by nickel ferrite nanoparticles as an efficient and magnetically reusable catalyst

Nickel ferrite magnetic nanoparticles (NiFe 2 O 4 MNPs) were prepared via the autocombustion assisted sol-gel method. The efficient catalyst was investigated by FT-IR, XRD, ICP, SEM, and TEM techniques. A one-pot, three-component reaction is reported for

Introduction of taurine (2-aminoethanesulfonic acid) as a green bio-organic catalyst for the promotion of organic reactions under green conditions

Taurine (2-aminoethanesulfonic acid), a semi-essential amino acid that exists in the human body and numerous other living creatures, is used as a green bio-organic catalyst for the promotion of the Knoevenagel reaction between aldehydes and malononitrile. In the same way, tetraketones can also be produced through a Knoevenagel reaction, followed by Michael addition. 2-Amino-3-cyano-4H-pyran derivatives are simply prepared via a three-component reaction in the presence of taurine as the catalyst. All these reactions are performed in water, a green solvent. The advantages of using of taurine as the catalyst are it is environmentally friendly, low cost, commercially available, easy to separate from the reaction mixture, and has high reusability. Use of this catalyst results in acceptable reaction times, high yields and high purities of the obtained products without utilizing any organic solvents.
