Developments in Organocatalysis Transformations of Unsaturated Pyrazolones
Doraghi F, Gilaninezhad F, Karimian S, Larijani B and Mahdavi M
Unsaturated pyrazolones can participate in organocatalytic reactions with various substrates to form spiro-cyclic pyrazolones, and fuzed-pyrazolone heterocycles. The present review describes progress since 2013 in the organocatalysis transformations of unsaturated pyrazolones. Pyrazolones are prevalent structural motifs in a wide variety of natural products and drug or drug-like molecules. A series of nitrogen-containing pyrazolones exhibits anticancer, antimicrobial, anti-inflammatory, anticonvulsant, antidepressant, antidiabetic, and antipyretic activities. Especially, chiral spiro-cyclic pyrazolones are recognized as targets in natural products and clinical pharmaceuticals. Organocatalytic systems are powerful and reliable approaches that allow us to build structurally complex molecules in an enantioselectively and diastereoselectively manner. Avoiding the use of transition metal catalysts, readily available bifunctional organocatalysts, and the performance of the reaction at ambient temperature are other advantages of these catalytic systems. Despite considerable progress in this field, it is still one of the challenging goals for chemists to make new biologically active heterocyclic molecules.
Co(CO) as a CO-source for Pd-catalyzed Carbonylations: An Update
Das D and Bhanage BM
Palladium-catalyzed carbonylative cross-coupling reactions with various carbon monoxide (CO) sources cultivate competent routes for the synthesis of bulk and value-added chemicals. However, the practical use of this odorless, inflammable, lethal gas has always raised a concern for chemists. The attention and advancement of various CO-surrogates is surely welcomed as a green alternative to CO-gas. However, the main concern lies in the suitability and scalability of these CO-surrogate-driven reactions. Literature showed the progress of various ways to make CO from these CO surrogates. One of the most convenient sources is using metal carbonyls which are already known to lose CO easily. Among all the kinds, Mo(CO)6 gained much popularity but its toxic nature and demand for high temperatures restricted its use. However, Co(CO) is popular as a catalyst but as an CO-source reports are scarce. This low-melting CO-releaser was found effective in flourishing aminocarbonylation, alkoxycarbonylation, and reductive carbonylation under mild conditions. This mini-review portrays the recent developments of palladium-catalyzed carbonylation reactions using Co(CO) as a CO source.

A Decade of Catalytic Progress in 1,4-Dihydropyridines (1,4-DHPs) Synthesis (2016-2024)
Soni A, Sharma M and Singh RK
1,4-Dihydropyridines (1,4-DHPs) are highly versatile and bioactive compounds known for their pharmacological properties, including cardiovascular, anticancer, and antioxidant activities. Traditional synthesis methods often involve harsh conditions, such as high temperatures, toxic reagents, and lengthy reaction times, leading to poor yields and environmental concerns. Consequently, there has been a growing focus on developing more sustainable, efficient, and eco-friendly alternatives for their synthesis. Among these, the catalytic one-pot multicomponent reaction (MCR) method has emerged as a promising strategy, offering high efficiency. Catalysts play a crucial role in enhancing reaction efficiency and selectivity, with various systems-metal-based, organocatalysts, polymer-supported catalysts, and enzymatic catalysts-each offering unique advantages. Metal catalysts provide high reactivity and selectivity, organocatalysts are more environmentally benign, polymer-supported catalysts offer improved stability and sustainability, and enzymatic catalysts enable highly specific reactions under mild conditions. However, challenges such as catalyst cost, reusability, scalability, and substrate scope remain. This review examines catalytic strategies for 1,4-DHPs synthesis from 2016 to 2024, highlighting reaction conditions, substrates, and yields. The analysis aims to inspire further exploration of new catalytic methods, expanding the application of 1,4-DHPs in medicinal chemistry.
