In the present work synthesis of 2-chloroquinoline-3-carbaldehydes (1a-g), 2-chloro-3-(1, 3-dioxolan-2-yl)quinolines (2a-g) and antioxidant activity using the DPPH assays is reported. The results showed that the compounds 1b, 1c, 2b, 2e, 2f possessed 84.65 to 85.75 % radical scavenging activity where as compound 1g showing 92.96% radical scavenging activity.

A series of 2-(3,5-substituted-1H-pyrazol-1-yl)-3-substituted quinolines 5a–g, were obtained from 2-chloro-3-(1,3-dioxolan-2-yl) quinolines 2a–c and diketones 3a–c with great yields by utilizing Montmorillonite clay K-10 as a catalyst in an eco-friendly methodology. All the synthesized compounds were characterized by FTIR, 1H-NMR, 13C-NMR and HRMS spectral techniques. Antibacterial screening of the
