Structures of Benzenesulfonylamino-3-(4-benzenesulfonyloxy-phenyl)-propionic acid and 2-(toluene-4-sulfonylamino)-3-[4-(toluene-4-sulponyl-oxy)-phenyl]-propionic acid: Variations in L-tyrosine Backbone Conformation, Intramolecular Aromatic π–π Stacking and Short C–H···O Interactions

Structures of Benzenesulfonylamino-3-(4-benzenesulfonyloxy-phenyl)-propionic acid and 2-(toluene-4-sulfonylamino)-3-[4-(toluene-4-sulponyl-oxy)-phenyl]-propionic acid: Variations in L-tyrosine Backbone Conformation, Intramolecular Aromatic π–π Stacking and Short C–H···O Interactions

The syntheses and crystal structures of benzenesulfonylamino-3-(4-benzenesulfonyloxy-phenyl)-propionic acid (1) and 2-(toluene-4-sulfonylamino)-3-[4-(toluene-4-sulponyloxy)-phenyl]-propionic acid (2) are described. The L-tyrosine cores of the molecules show significant conformational differences. In...
