diazomethylphosphonate leading to the formation of two different types of products is reported. The reaction carried out in acetone in the presence of catalytic amount of cesium fluoride afforded spiropyrazoline phosphonates via 1,3-dipolar cycloaddition reaction, whereas the reaction in methanol yielded an interesting class of pyrazolylphthalides. This strategy provides an efficient alternative method
against α and β-glucosidase enzymes and found encouraging results. The current study comprises of evaluation of indane-1,3-dione as antidiabeticagents based on our previously reported results obtained from closely related moiety isatin and its derivatives. Objective: A library of twenty three indane-1,3-dione derivatives (1-23) was synthesized and evaluated for α and β-glucosidase inhibitions. Moreover

3-dione and its derivatives are important building blocks in organic synthesis and present important biological activities. Herein, the leishmanicidal and cytotoxicity evaluation of 16 2-arylidene indan-1,3-diones is described. The compounds were evaluated against the leukemia cell lines HL60 and Nalm6, and the most effective ones were 2-(4-nitrobenzylidene)-1H-indene-1,3(2H)-dione (4) and 4-[(1,3

A basepromoted diastereoselective formal [3+3] cycloaddition reaction of 2-arylideneindan-1,3-diones with β-naphthols towards the synthesis of functionalized pentacyclic indeno[1], [2], [2](a), [2](b)chromen-(4bH)-ones has been developed. This methodology is appreciated in terms of diastereoselectivity and mild conditions. In addition, the immunosuppressive assay indicates that one of the products
Palladium-Catalyzed Asymmetric [3+2] Cycloaddition of Vinylethylene Carbonates with 2-Arylidene-1,3-Indandiones: Synthesis of Tetrahydrofuran-Fused Spirocyclic 1,3-Indandiones
An asymmetric [3+2] cycloaddition of 2‐arylidene‐1,3‐indandiones with vinylethylene carbonates in the presence of Pd2dba3· CHCl3 and axially chiral phosphoramidite ligand was developed.
