Abstract A highly efficient and green protocol for the synthesis of pyrimido[4,5-b]quinolines has been described. The one-pot multicomponent reaction of dimedone with arylaldehydes and 6-amino-1,3-dimethyluracil in the presence of N,N-diethyl-N-sulfoethanaminium chloride ([Et3N–SO3H][Cl]) as an ionic liquid (IL) catalyst under solvent-free conditions afforded the mentioned compounds in high yields and short reaction times. Our protocol is superior to many of the reported protocols in terms of two or more of these factors: the reaction times, yields, conditions (solvent-free versus usage of organic solvents), temperature and catalyst amount.

: A green and efficient protocol was developed for the one-pot three-component synthesis of novel 2-(4-hydroxy-2-oxo-2H-chromen-3-yl)-2-(arylamino)-1H-indene-1,3(2H)-dione derivatives by the reaction of 4-hydroxycoumarin, ninhydrin and aromatic amines in the presence of guanidine hydrochloride as an organocatalyst under solvent-free conditions. The present approach offers several advantages such as low cost, simple work-up, short reaction times, chromatography-free purification, high yields and greener conditions.

: NiO nanoparticles are utilized to effectively strengthen annulated pyrano [2, 3- d] pyrimidine synthesis through primary Knoevenagel, following Micheal and ultimate heterocyclization reactions of aldehyde, malononitrile, and barbituric acid. The characteristics of NiO nanoparticles are identified using advanced techniques, such as IR, UV, EDX, XRD, SEM, and TEM. The nano-NiO particles are mostly below < 100 nm in size with uniform spherical shapes. The adopted approach is advantages thanks to its simple processing, relatively short reaction time, often good to high average yields, convenient workability, and environmental friendliness.
