- A one-pot green synthesis of 2-amino-4H-benzo[h]chromenes catalyzed by a dioxomolybdenum Schiff base complex supported on magnetic nanoparticles as an efficient and recyclable nanocatalyst
-
In this work, catalytic performance of a molybdenum Schiff base complex-supported magnetic support as a nanocatalyst was evaluated for the preparation of 2-amino-4H-benzo[h]chromenes through one-pot, three component reactions of 1-naphthol, various aldehydes, and malononitrile under solvent-free conditions. A promising greener and eco-friendly method with a short reaction time, high yield of products, and simple work-up procedure was achieved. The nanocatalyst could be easily separated and regenerated from reaction media by an external magnet and reused at least seven consecutive times with small drops in its catalytic performance.

- A molybdenum(VI) Schiff base complex immobilized on functionalized Fe3O4 nanoparticles as a recoverable nanocatalyst for synthesis of 2-amino-4H-benzo[h]chromenes
-
A dioxomolybdenum(VI) complex of a Schiff base, immobilized on the surface of modified Fe3O4 with a silica coating, has been synthesized and characterized by spectroscopic and microscopic techniques including FTIR, TGA, ICP, SEM, EDX, VSM, and XRD analyses. The catalytic performance of this material has been evaluated for the preparation of 2-amino-4H-benzo[h]chromenes via the one-pot, three-component reaction of aldehydes, malononitrile, and 1-naphthol under solvent-free conditions. The benefits of this protocol are short reaction time, simple workup procedure, and high yields of products. Also, the synthesized nanocatalyst could be separated easily from the reaction mixture using an external magnet and reused for four consecutive times with only minor degradation of its catalytic performance.

- Aqua one-pot, three-component synthesis of dihydropyrano[3,2-c]chromenes and amino-benzochromenes catalyzed by sodium malonate
-
The widespread biological properties of dihydropyrano[3,2-c]chromenes, 2-amino-4-aryl-4H-benzo[h]chromenes, and 3-amino-1-aryl-1H-benzo[f]chromenes have led to increasing efforts for the development of tremendously effective synthetic protocols aimed at their synthesis. In this contribution, sodium malonate was employed for the first time as an efficient catalyst for the one-pot, three-component tandem Knoevenagel–cyclocondensation reaction of 4-hydroxycoumarin (or naphthols), malononitrile/ethyl cyanoacetate, and various aldehydes. These compounds underwent Knoevenagel–Michael–Thorpe–Ziegler cyclization upon heating at 70?°C in water to give the respective medicinally relevant dihydropyrano[3,2-c]chromenes and amino-benzochromenes. The method is versatile and amenable to many substrates as it requires no specialized devices such as microwave, ultrasound and ball-milling. Also, the salient features of this high-yielding protocol are green reaction conditions, the use of commercially available catalyst, easy purification processes by a simple filtration, and relatively shorter reaction times.

The effects of nature and amount of ionic liquids on the yield and reaction time were thoroughly investigated. The ionic liquids showed a considerable level of reusability without a significant decrease in catalytic activity. We have successfully combined the advantages of microwave technology with ionic liquids to facilitate the rapid construction of chromene skeletons from readily obtainable and inexpensive materials via a multicomponent strategy.

- Efficient tandem synthesis of a variety of pyran-annulated heterocycles, 3,4-disubstituted isoxazol-5(4H)-ones, and α,β-unsaturated nitriles catalyzed by potassium hydrogen phthalate in water
-
A variety of 4H-chromenes, benzochromenes, 4,5-dihydropyrano[3,2-c]chromenes, 4H-pyran-3-carboxylates, and 3,4-disubstituted isoxazol-5(4H)-ones have been synthesized in high yields by using potassium hydrogen phthalate (KHP) as an inexpensive, commercially available catalyst. It was found that the three-component tandem reaction enabled synthesis of pyran-annulated heterocycles in water at 50 °C. 3,4-Disubstituted isoxazol-5(4H)-ones were synthesized by use of 10 mol% KHP in water at room temperature. Also, treatment of methylene-containing compounds (malononitrile or ethyl cyanoacetate) with aromatic aldehydes in the presence of 5 mol% KHP resulted in α,β-unsaturated nitriles. The procedure is an easily performed, straightforward method for synthesis of a variety of pyran-annulated compounds, isoxazol-5(4H)-one-containing heterocycles, and Knoevenagel adducts. The reaction is safe, uses mild conditions, and is environmentally benign. Other notable advantages are reuse of the catalyst, no use of hazardous organic solvents, and ease of work-up.
