Four-component clean process for the eco-friendly synthesis of 1H-pyrazolo [1,2-b]phthalazine-5,10-dione derivatives using Zn(OAc)(2)center dot 2H(2)O as an efficient catalyst under solvent-free conditions

An efficient and convenient zinc acetate dihydrate (Zn(OAc)(2)center dot 2H(2)O) catalyzed synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-dione derivatives has been accomplished via one-pot four-condensation of phthalic anhydride, hydrazine monohydrate, aromatic aldehydes derivatives and malononitrile under solvent-free conditions. The notable advantages of the present procedure are: operational simplicity, eco-friendly, environmentally benign nature, low-cost and non-toxic catalyst, no necessity of chromatographic purification steps, short reaction times and good to high yields.

Sulfonated Magnetic Nanoparticles as Recyclable Catalyst for Facile One-Pot Green Synthesis of 3,4-Dihydro-2H-indazolo[1,2-b]phthalazine-1,6,11(13H)-trione Derivatives

Sulfonated magnetic nanoparticles (SO3H-Fe3O4@SiO2 MNPs) have been explored as an efficient, cost-effective, and recyclable nanocatalyst for the facile synthesis of 3,4-dihydro-2H-indazolo[1,2-b]phthalazin-1,6,11(13H)-triones through a one-pot three-component reaction between aldehydes, dimedone, and phthalhydrazide under mild and green (solvent-free) conditions. Simple separation of the catalyst using an external magnet, efficient recyclability of the developed magnetic nanocatalyst up to five fresh runs without significant loss in its catalytic activity, excellent yields of the designed reactions (88 to 98%), low reaction times as well as solvent-free and facial reaction condition are some advantages of the present procedure that qualified the fabricated magnetic nanocatalyst for industrial applications.

Design, Regiospecific Green Synthesis, Chemical Computational Analysis, and Antimicrobial Evaluation of Novel Phthalazine Heterocycles

Phthalazines have received considerable attention for their wide antimicrobial activity. Regiospecific nucleophilic attack of 4-benzylphthalazin-1-ol by the 1-oxo rather than the aza group on different alkyl halides gave novel phthalazine heterocyclic derivatives. Moreover, a variety of nucleosides bonded to electron-withdrawing groups were synthesized using 4-benzylphthalazine-1-ol. The density functional theory has been used to investigate the electronic structure of the synthesized compounds. All of the synthesized derivatives showed remarkable activity when tested against Gram-positive and Gram-negative bacteria, Aspergillus niger, and Candida albicans. The reactivity of these nucleosides was expected to arise from their bonding with the lone pair of N-atom of the macromolecules of bacteria. These bonding were expected to inhibit the enzyme by forming highly stable complex with lower highest occupied molecular orbital energy. The structures of these synthesized derivatives were established by Fourier transform infrared, H-1-NMR, and C-13-NMR spectroscopic evidence.
