series of new spiro-condensed 2-amino-4H-pyrans were synthesized by three-component interaction of 1,2-benzoxathiin-4(3H)-one 2,2-dioxide, malononitrile, and cyclic carbonyls in moderate to high yields. This is one of the first examples of 1,2-benzoxathiin-4(3H)-one 2,2-dioxide application in multicomponent transformations.

vitro calf thymus DNA (ct-DNA) binding ability of compounds 4c, 4f, 4i, 4l, 4 m, 4n, and 4o was evaluated via ultraviolet-visible and fluorescence spectroscopy techniques. A hyperchromic effect was observed with no apparent wavelength shift which predicted for the groove binding mode. A moderate binding constant for 4o, in fluorescence results, confirms groove binding. The molecular docking of 4o with
Multicomponent synthesis of mono and bis‐spiropyrazolopyridines from isatin derivatives, indanedione, and 3‐methyl‐5‐aminopyrazole under microwave irradiation in the absence of any catalyst or solvent with high yield and short reaction time is reported.

Polymethylene-linked isatin dimers 1a-g and 3-indolyl-3-hydroxy-2-oxindole dimers 2a-g were synthesized and are reported here as selective butyrylcholinesterase (BChE) inhibitors. The best compound from each series, 1f and 2d, showed IC50 values of 3.20 µM and 4.49 µM, respectively. Both compounds showed > 11-fold selectivity towards BChE, and mixed-type inhibition by Lineweaver-Burk analysis. These
