Adducts AlCl3.RCOCl undergo highly regioselective self- and cross-condensation. 4-Hydroxy-2-pyrones and 2-acetyl-indan-l,3-diones are synthesized in good yields.

Benzothiazolyl hydrazones are synthesized and tested as hypoglycemic and antimicrobial agents. Condensation of 2-acyl-(1H)-indene-1,3(2H)-diones with 2-hydrazinylbenzo[d]thiazole/2-hydrazinyl-6-substitutedbenzo[d]thiazoles gives the corresponding hydrazones in high yields. Preliminary biological assay of the products reveals significant antidiabetic and antimicrobial activities. The α-amylase and α-glucosidase inhibition assay is used for determination of Type II diabetes inhibitory activity.

A series of M(II) (M = Cu, Zn, Cd, Pb) complexes with the physiologically active 1-acetylindan-1,3-dione were synthezed. All complexes were obtained with the metal to ligand ratio 1:2. The presence of two water molecules in the inner coordination sphere of the Zn(II) and Cd(II) complexes was proven. The structure and coordination mode of the newly synthesized Cd(II) and Pb(II) complexes were investigated using NMR (13C CPMAS and 13C NMR in DMF-d7 solution) method. Semi-empirical (PM3) and ab initio (ECP-312G) calculations of the structure and IR spectra of the free ligand and corresponding metal(II) complexes were performed. It is shown that the structure of the Pp(II) complex differs significantly from the distorted tetrahedral structure of the Cu(II), Zn(II), and Cd(II) complexes.

A series of thiazole tethered indenopyrazoles has been synthesized and assayed for their antimicrobial and α-amylase inhibitory activities. Ciprofloxacin and Fluconazole were used as standard drugs for antibacterial and antifungal evaluation, respectively while Acarbose was used as standard reference for α-amylase inhibitory activity. The antimicrobial activity evaluation results revealed that derivative 3d showed highest potency against two Gram-positive bacterial strains (Bacillus subtilis and Staphylococcus aureus), two Gram-negative bacterial strains (Escherichia coli and Pseudomonas aeruginosa) with MIC values of 0.0541 μmol/mL, 0.0270 μmol/mL, 0.0270 μmol/mL, 0.0270 μmol/mL, respectively and two fungal strains (Candida albians and Aspergillus niger) with MIC values of 0.0067 μmol/mL and 0.0270 μmol/mL, respectively in comparison to the standard drugs Ciprofloxacin (MIC = 0.0094 μmol/mL) and Fluconazole (MIC = 0.0408 μmol/mL). Interestingly, all the compounds of the series except 3e exhibited better inhibitory activity against C. albicans with MIC value ranging from 0.0067 to 0.0297 μmol/mL than the standard drug Fluconazole. However, derivatives 3j with IC50 value of 0.79 μM and 3k with IC50 value of 0.46 μM were recognized as good α-amylase inhibitors as compared to the reference drug Acarbose (IC50 = 0.11 μM). Further, the docking studies were performed to support the results of biological activities.

We report a convenient and efficient synthesis of indeno[1,2-c]pyrazol-4(1H)-ones (4a?o) by the reaction of a variety of 2-acyl-(1H)-indene-1,3(2H)-diones (1) and 2-hydrazinylbenzo[d]thiazole/2-hydrazinyl-6-substitutedbenzo[d]thiazoles (2) in the presence of glacial acetic acid in good yields. The structure of the compounds thus prepared were confirmed by analytical and spectral (FT-IR, 1H NMR, 13C NMR, and HRMS) techniques. All the synthesized indeno[1,2-c]pyrazol-4(1H)-ones (4a?o) were assayed for their in vitro Type II diabetes inhibitory activity by using Acarbose as standard drug and in vitro antimicrobial activity utilizing Streptomycin and Fluconazole as reference drugs. Among the synthesized derivatives, 4e (IC50 = 6.71 μg/mL) was found to be more potent against α-glucosidase enzyme as compared with the standard Acarbose (IC50 = 9.35 μg/mL) and 4i (IC50 = 11.90 μg/mL) exhibited good inhibitory activity against α-amylase enzyme as compared with the standard Acarbose (IC50 = 22.87 μg/mL). Also, all the titled compounds showed good antimicrobial activity. In addition, in vitro α-glucosidase and α-amylase inhibition were supported by docking studies performed on the derivatives 4e and 4o, respectively. [Figure not available: see fulltext.].
Acylation of Aroyl Chlorides via a Template Friedel-Crafts Process: Synthesis of Indan-1,3-diones

Variously substituted indan-1,3-diones have been regioselectively prepared in a one-pot synthesis by sequential cross-condensation-cycloacylation of aromatic acyl chlorides and acetyl chloride or malonyl dichloride, electrophilic acylation of aromatic acyl chlorides representing the key step in the process.The synergism of the aromatic carbonyl enolization and the organization of the reacting system promoted by the metal is emphasized to account for the mild reaction conditions.
