Abstract

To understand the driving forces of aromatic stacking interactions in water, we have performed conformational searches, molecular dynamics simulations, potential of mean force (PMF) and free energy perturbation (FEP) calculations, syntheses, and NMR studies on sodium (2, 2)-bis (indol-1-yl-methyl) acetate (1), sodium 3-indol-1-yl-2-methyl-propionate (2), and sodium 3-indol-1-yl-propionate (3). The conformational searches on 1 revealed ...
