Anticancer Polymers via the Biginelli Reaction [PDF]

open access: yesACS Macro Letters, 2020
We developed a polymer-drug strategy to explore anticancer polymers. A series of monomers containing groups with potential anticancer activity have been facilely prepared through the Biginelli reaction. These monomers were used to produce water-soluble polymers through convenient radical copolymerization.

A Five-Component Biginelli-Diels-Alder Cascade Reaction [PDF]

open access: yesFrontiers in Chemistry, 2018
A new multi-component condensation was discovered during the reaction of a urea, β-keto ester, and formaldehyde. In the presence of catalytic indium bromide, a Biginelli dihydropyrimidinone intermediate was further converted to a five-component ...

Modification of Starch via the Biginelli Multicomponent Reaction [PDF]

open access: yesMacromolecular Rapid Communications, 2019
AbstractAn efficient and straightforward modification of starch using renewable and commercially available aromatic aldehydes (benzaldehyde, vanillin, and p‐anisaldehyde) and urea via the Biginelli multicomponent reaction is reported in this work. First, starch acetoacetate (SAA) with a degree of substitution ranging from 1.4 to 2.5, depending on the ...

Microwave-Assisted Biginelli Reaction: An Old Reaction, a New Perspective [PDF]

open access: yesCurrent Organic Synthesis, 2016
In this review, we tried to highlight the recent advances in the Biginelli reaction, leading to the synthesis of 3,4-dihydropyrimidin-2(1H)-ones, albeit only those conducted under microwave irradiation. The merits and drawbacks of these reactions are compared and discussed with those performed under conventional heating.

A mini-review on Biginelli adducts with notable pharmacological properties [PDF]

open access: yesJournal of Advanced Research, 2015
Since the disclosure of Biginelli reaction by the chemist Pietro Biginelli, functionalized 3,4-dihydropyrimidin-2(1H)-ones/thiones (DHPMs) have emerged as prototypes for the design of compounds with a broad variety of biological activities.

A four-component modified Biginelli reaction: A novel approach for C-2 functionalized dihydropyrimidines. [PDF]

open access: yesTurk J Chem, 2021
A novel four component modified Biginelli reaction for the synthesis of C-2 functionalized dihydropyrimidines has been established. The approach uses assembly of less explored acetyl acetone with aromatic aldehyde, thiourea, and dimethyl sulphate to ...

A copper-doped ZIF-8: a high-performance catalyst for eco-friendly Ullmann and Biginelli reactions. [PDF]

open access: yesSci Rep
Metal-organic frameworks (MOFs) with high porosity have gained significant interest in organic reactions. In this study, copper-doped ZIF-8 (Cu-ZIF-8) was synthesized at room temperature, followed by oven drying at 60 °C, and subsequently employed as a ...

Piperazine-grafted magnetic graphene oxide as a sustainable heterogeneous catalyst for solvent-free Biginelli reaction. [PDF]

open access: yesRSC Adv
Multi-component reactions (MCRs) are powerful tools for the one-pot synthesis of complex organic compounds, with the Biginelli reaction being one of the most important due to its versatility in synthesizing a wide range of dihydropyrimidine-2-ones (DHPMs)
