A highly diastereoselective spiro-cyclopropanation reaction of 2-arylidene-1,3-indanediones and dimethylsulfonium ylides has been developedviabase-induced annulation. This efficient and simple protocol features simple operations, mild conditions and excellent functional group compatibility. A variety of structurally interesting spiro-cyclopropanes were prepared in excellent yields and diastereomeric ratios (up to 97% yield and 20?:?1 dr). Also, ring expansion of the cyclopropanation product to quickly deliver a complex indeno[1,2-c]pyridazine structure showcased an interesting application of this method.

A series of seventeen 3-aryl-1-heteroarylindeno[1,2-c]pyrazol-4(1H)-ones (4a, 4b, 4c, 4d, 4e, 4f, 4g, 4h, 4i, 4j, 4k, 4l, 4m, 4n, 4o, 4p, 4q) has been synthesized and characterized by spectral (IR, 1H NMR, and mass), X-ray crystallography and analytical results. All the indenopyrazoles (4a, 4b, 4c, 4d, 4e, 4f, 4g, 4h, 4i, 4j, 4k, 4l, 4m, 4n, 4o, 4p, 4q) were tested for their in vitro antimicrobial activity against two Gram-positive bacteria viz. Bacillus subtilis (MTCC 441) and Staphylococcus aureus (MTCC 7443), two Gram-negative bacteria, viz. Escherichia coli (MTCC 42) and Pseudomonas aeruginosa (MTCC 741) and two fungi, viz. Candida albicans (MTCC 183) and Aspergillus niger (MTCC 282) using ceftriaxone and fluconazole as standard references against bacterial and fungal strains, respectively. Among the synthesized derivatives, 4f against B. subtilis and S. aureus, 4e against E. coli, 4g and 4j against P. aeruginosa, 4k and 4l against C. albicans, and 4k against A. niger were found to exhibit appreciable antimicrobial activities. However, 4g (minimum inhibitory concentration, 0.0036 μmol/mL) was found to be more potent than the reference, that is, fluconazole (minimum inhibitory concentration, 0.0050 μmol/mL) against A. niger. Moreover, both antibacterial and antifungal activities were found to be prolific. The radial distribution function parameters were found to be important for description of activities against the modeled strains in quantitative structure–activity relationship studies.

An unexpected product-selectivity in the reaction of 2-arylideneindane-1,3-dione with dimethyl 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 for the construction of pyrazolylphthalides, and moreover, the process is general, works under mild conditions, and exhibits high functional group compatibility.
