Efficient sonochemical protocol for the facile synthesis of dipyrimido-dihydropyridine and pyrimido[4,5-d]pyrimidines in aqueous β-cyclodextrin

An economical and efficient synthesis of dipyrimido-dihydropyridines and pyrimido[4,5-d]pyrimidines is described using greener and recyclable β-cyclodextrin as a supramolecular catalyst in aqueous medium. The remarkable features of this method are mild reaction conditions, short reaction times, easy workup procedure, recyclability of the catalyst, and excellent yields of the products. The highly functional group tolerance and shorter reaction times make this method suitable for the synthesis of dihydropyridine and pyrimido[4,5-d]pyrimidine derivatives with a wide substitution pattern.

Verjuice as a green and bio-degradable solvent/catalyst for facile and eco-friendly synthesis of 5-arylmethylenepyrimidine-2,4,6-trione, pyrano[2,3-d]pyrimidinone and pyrimido[4,5-d]pyrimidinone derivatives

Verjuice (unripe grape juice), a natural mixture of organic acids, which is identified by pH-metric and TGA analysis, is efficiently used for the promotion of the synthesis of 5-arylmethylenepyrimidine-2,4,6-triones, via Knovenagel condensation reaction between barbituric or thiobarbituric acid and aldehydes. Verjuice is also employed for the effective synthesis of pyrano[2,3-d]pyrimidinone derivatives via a three-component reaction of barbituric acid or its thio analogue, aldehydes and malononitrile. In the same way, pyrimido[4,5-d]pyrimidinone derivatives are simply produced via the reaction of barbituric acid, aldehydes and urea or thiourea in the presence of verjuice. This green methodology rewards notable advantages including simple procedures, acceptable reaction times, easy work-up, high yields, circumventing the use of any expensive starting materials, volatile and hazardous organic solvents during the reaction and work-up process, and use of a natural, low-cost, reusable, and bio-degradable catalyst.

Facile and simple synthesis of pyrimido[4,5-d]pyrimidinones and pyrano[2,3-d]pyrimidinones catalyzed by nano-sized NS-C4(DABCO-SO3H)2·4Cl

In this work, 4,4′-(butane-1,4-diyl)bis(1-sulfo-1,4-diazabicyclo[2.2.2]octane-1,4-diium)tetrachloride (NS-C4(DABCO-SO3H)2·4Cl), a newly reported nano-sized Br?nsted acid catalyst is used for the effective synthesis of pyrimido[4,5-d]pyrimidinones and pyrano[2,3-d]pyrimidinones derivatives. The products were formed under mild and environmentally friendly conditions in excellent yields over very short reaction times. Using green solvent and simple methodologies, no side reactions and use of inexpensive catalyst with lower loading are other advantages of this work.
