Stretched gelatin has been known as a chiral discriminator in aqueous solution for several years, as measured by differences in anisotropic NMR parameters like residual dipolar couplings. The extension of the method to higher temperatures and the important solvent DMSO by cross‐linking gelatin with accelerated electrons potentially opens the field to a variety of polar chiral molecules (see figure).
