Thiocoumarins and dithiocoumarins are two important classes of sulphurcontaining heterocyclic compounds, which are bioisosteres of coumarins. Herein, various synthetic strategies for these two classes of heterocyclic compounds reported in the literature have been discussed. Different solvents, catalysts, reagents and reaction conditions, which were employed successfully for synthesizing thiocoumarins and dithiocouma Read More

The quinoline moiety is a privileged scaffold among heterocyclic compounds that is an important construction motif in the fields of pharmaceutical chemistry. Quinoline molecule possesses a variety of therapeutic activities like antiviral, antimalarial, antibacterial, antitumor, anticancer, antioxidant antihypertensive, antifungal, anthelmintic, cardiotonic, anticonvulsant and anti-inflammatory. This review provides an insight Read More

With their ability to dissolve inorganic as well as organic materials, ionic liquids have emerged as a versatile solvent system for a diverse range of organic transformations. In the past few decades, the literature has witnessed remarkable advances in a wide range of organic conversions carried out in the presence of various imidazolium, pyridinium, pyrrolidinium, quinolinium and diazobicyclo-octane based ionic liquids. In the rea Read More

Biofuel synthesis is of great significance for producing alternative fuels. Among the developed catalytic materials, the metal-organic framework-based hybrids used as acidic, basic, or supported catalysts play major roles in the biodiesel production. This paper presents a timely and comprehensive review of recent developments on the design and preparation of metal-organic frameworks-based catalysts used for bio Read More

[1,2,4]Triazolo[3,4-b]quinazolin-5(1H)-ones with varied functionalization patterns were synthesized in a regioselective manner by reacting 2-thioxo-2,3- dihydroquinazolin-4(1H)-one (2) with variously functionalized hydrazonoyl chlorides (3ah). Linear regioselectivity of the formed products was confirmed by X-ray measurements. Under microwave conditions, the reactions were completed in a few minutes without a change in th Read More
