“…Biscoumarin, a bridged dimer of 4-hydroxycoumarin, has been reviewed [6] and reported with its vast pharmaceutical activities such as anticancer [7][8][9][10], anticoagulant [11], antioxidant [12,13], urease inhibitory activity [14], Zika virus inhibitor [15], antiviral [16], inhibition of α-glucosidase [17], antimicrobial activity [18][19][20][21][22], antilipoxygenase activity [23], inhibition of snake venom [24], inhibition of HIV integrase [25] and proliferation inhibition of K-562 [26]. Despite its pharmacological applications, they are also employed in industrial applications as fluorescent and colorimetric sensors [27], ligands [28], semiconductors [29], photoluminescent [30] and designing of WLED [31]. Another moiety, tetraketones are valuable in the organic synthetic field as multifaceted precursors in the production of tricyclic heterocycles, viz.…”

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.

Biscoumarin has emerged as one of the most unique and valuable moiety in the field of synthetic as well as in medicinal chemistry. This moiety has been examined for the designing of potent derivatives and hybrids with other moieties and substituents exhibiting a myriad of medicinal properties. These far‐flung characteristics enthralled the researchers to discover various methods for the synthesis of biscoumarin nucleus and its derivatives from 4‐hydroxycoumarin and varieties of aldehydes using different types of catalysts to improve the selectivity, purity and yield of the products. Moreover, liberal scope is available for this structural unit which needs to be explored by chemists for the advancement of new potential drug candidates. This article summarizes the current eco‐benign pathways for the synthetic strategies of biscoumarins under various reaction conditions viz. solid supported catalyst, ionic liquid, nanoparticles, Lewis acid, heteropolyacids, nanocomposites etc.
