“…(1R*,2R*)-Di-tert-butyl N,N 0 -(cyclohexane-1,2-diyl)dicarbamate, (I), was synthesized as part of our ongoing studies into enantioselective recognition (Botana et al, 2001;Rossi et al, 2002;Kyne et al, 2001). The synthesis of new chiral receptors is a major challenge for chemists since it is very difficult to predict all the factors contributing to the binding process between a host and a guest in solution (Beer et al, 1999).…”
