In recent years, indole derivatives have acquired conspicuous significance due to their wide spectrum of biological activities-antibacterial, antiviral, and anticonvulsant. This compound is derived from naturally grown plants. Therefore, synthesis of a novel 3-(Naphthalen-1-ylimino)indolin-2-one compound (2) and its analysis using UPLC systems along with antimicrobial assessment was the aim of the current study. Isatin was used as a parent drug for synthesizing compound (2). Liquid Chromatographic analysis was performed using a C18 BEH column (1.7 mu m 2.1 x 50 mm) by UPLC systems. Degradation studies were carried out to see whether acid, base, thermal, and oxidizing agents had any impact on the synthesized molecule in stress conditions (100 degrees C). A lipid-based self-nanoemulsifying formulation was developed and selectivity, specificity, recovery, accuracy, and precision were measured as part of the UPLC system’s validation process. Antimicrobial studies were conducted using gram-positive and gram-negative bacteria. The standard samples were run with a concentration range of 5.0-100.0 mu g/mL using the isocratic mobile phase comprising of methanol/water (70/30 %v/v) at 234 nm; good linearity (R-2 = 0.9998) was found. The lower limits of detection (LOD) and quantitation (LOQ) of the method were found to be 0.81 mu g/mL and 2.5 mu g/mL, respectively. The coefficients of variation were found to be less than 2%. The antimicrobial study suggests that compound (2) has a substantial growth effect against gram-negative bacteria. It was successfully synthesized and applied to measure the concentrations in lipid-based dosage form, along with potent antimicrobial activities.

Herein, a divergent synthesis of a variety of 2 alpha- and 5 alpha-substituted furan derivatives from 2-hydroxy-1,4-diones is reported. By using appropriate substrates and an acid catalyst, the reactions occurred selectively through cyclization/1,6-conjugate addition or cyclization/Friedel-Crafts-type cascade reactions. A broad range of nucleophilic reagents (>10 types for the 1,6-conjugate addition for 5 alpha substitution and >20 types for the Friedel-Crafts-type cascade reaction for 2 alpha substitution), including alcohols, amides, furan, thiophene, pyrrole, indole, phenols, and many others, can successfully participate in the reactions, providing a universal strategy for a diversity-oriented synthesis of alpha-substituted furan derivatives. Deuteriation experiments and DFT calculations were carried out to support the proposed reaction mechanisms. Antifungal activity experiments revealed that products with an indole or 4-hydroxycoumarin core substituted at the 2 alpha position showed moderate activities against Rhizoctorzia solani and Botrytis cinerea, respectively.

A conformationally rigid chiral bicyclic skeleton tethered bipyridine-Zn(OTf)(2) complex facilitated the enantioselective Friedel-Crafts alkylation of indoles with trans-beta-nitroarylalkenes in an enantioselective manner at elevated temperature. Indoles reacted smoothly with beta-nitroarylalkenes to generate the corresponding 3-(2-nitroalkyl) indoles in good to excellent yields (up to 94%) with moderate to excellent enantioselectivities (up to 91%). The stereochemical outcome of the product from indole and trans-beta-nitrostyrene in the presence of the CRCB tethered bipyridine-Zn(OTf)(2) complex and the DFT calculation of the CRCB tethered bipyridine-Zn: trans-beta-nitrostyrene complex support the si-face attack of indole on trans-beta-nitrostyrene.
