“…In this process, an effective pathway for the synthesis of bisdimedones by the reaction of dimedone and aldehyde via Knoevenagel-Michael addition in solvent-free conditions at 110 C temperature using 0.001 g of SiO 2 nanoparticles as a catalyst under grinding was introduced by Alinezhad and co-workers [32]. The catalyst was prepared by mixing and stirring of tetraethoxysilane (TEOS) and 25% of aqueous ammonia in ethanol.…”

Bisdimedones have emerged as an important and versatile moiety in the field of synthetic and medicinal chemistry. It is screened as a precursor for the synthesis of several heterocycles such as acridinediones, xanthenediones, thioxanthenes, and benzopyrans that exhibited immense pharmacological as well as industrial applications. Its extensive characteristics have attracted the scientists to develop various protocols for the synthesis of bisdimedones and their derivatives from the reaction of dimedone with several aldehydes under different environmental conditions using various types of catalysts. This review encapsulates the recent progress in the synthesis of bisdimedone derivatives under several reaction protocols such as the use of nanoparticles, ionic liquids, metal salts, simple organic compounds, and catalyst-free conditions, and so forth in the last 20 years.

“…Solvent-free conditions, less reaction time, excellent yields, purification without use of column chromatography, and ecofriendliness are the additional benefits of this protocol (Scheme 9, Method 8). Alinezhad et al [103] demonstrated a simple, efficient, and solvent-free synthesis of 2,3-dihydro-1H-perimidines from NDA and aldehydes using SiO 2 nanoparticles via grind-stone technique at room temperature. In order to study optimization of reaction feasibility, the authors applied multiple solvents like H 2 O, CH 3 CN, EtOH, CH 2 Cl 2 , and THF in variation with a catalytic amount and temperature.…”

Perimidines are versatile scaffolds and a fascinating class of N-heterocycles that have evolved significantly in recent years due to their immense applications in life sciences, medical sciences, and industrial chemistry. Their ability of molecular interaction with different proteins, complex formation with metals, and distinct behavior in various ranges of light makes them more appealing and challenging for future scientists. Various novel technologies have been developed for the selective synthesis of perimidines and their conjugated derivatives. These methods extend to the preparation of different bioactive and industrially applicable molecules. This review aims to present the most recent advancements in perimidine synthesis under varied conditions like MW radiation, ultrasound, and grinding using different catalysts such as ionic liquids, acid, metal, and nanocatalyst and also under green environments like catalyst and solvent-free synthesis. The applications of perimidine derivatives in drug discovery, polymer chemistry, photo sensors, dye industries, and catalytic activity in organic synthesis are discussed in this survey. This article is expected to be a systematic, authoritative, and critical review on the chemistry of perimidines that compiles most of the state-of-art innovation in this area.

“…Moreover, bisdimedone derivatives have been synthesized using several catalysts, viz. acidic salt based on lipase TLIM [53], Na 2 CaP 2 O 7 [54], SiO 2 NPs [55], amino-appended β-cyclodextrins (ACDs) [56], Fe 3 O 4 @SiO 2 @Ni-Zn-Fe LDH [57], GO/ZnO [58], ZnS NPs [59], BiOCl NPs [60] and natural phosphate [61]. Even though most of the described methods are useful, they have some limits including harsh reaction conditions, costly catalyst preparation procedure, low yields, prolonged time of reaction, tedious work-up, application of hazardous and expensive reagents and solvents.…”

In this study, a simple, cost-efficient and green protocol has been described for the synthesis of biscoumarin and bisdimedone derivatives via one-pot Knoevenagel-Michael reaction of aromatic aldehydes with 4-hydroxycoumarin and dimedone, respectively. This approach has defined a new way of synthesizing products (4a-i and 5a-i) in high yields using carbon sulfonic acid as a heterogeneous solid acid catalyst. All the reactions have been executed in a greener medium in short reaction times with high-to-excellent yields. This organic synthesis adheres to the principles of green chemistry as the catalyst is cheap, gentle toward environment, easy to handle and reusable up to six cycles, easily separable through filtration, green reaction media and high yield of derivatives in short reaction time. The structure of the synthesized compounds was established by spectral analysis.
