Synthesis and Spectral Characterisation of (E)-3-(3-(4 (Dimethylamino)Phenyl)Acrylo-yl)-4-Hydroxy-2H-Chromen-2-One and Their Antibacterial Activity and Acetylcholinesterase Inhibition

<div>Optimized structures of the keto (<b>A</b>) and enol (<b>B</b>) tautomers of coumarin <b>3</b> and their charge distributions. The arrows indicate the direction of the dipole moment for each tautomer that was determined using the B3LYB/6-31G(d) level of theory. The lengths along the dipole-moment directions give the relative magnitudes of dipole moments for both tautomers.</div>
