D. Ranganathan et al., SELF-ASSEMBLING UREA-BASED PEPTIDOMIMETICS - A SIMPLE ONE-STEP SYNTHESIS AND CRYSTAL-STRUCTURE OF CORE BETA-ALANYL UREYLENE RETRO-BISPEPTIDES (MEO-A(AA)-[NH-CO-NH]-CH2-CH2-CO-NH-A(AA)-OME, A(AA)=AMINO-ACID-A), Tetrahedron letters, 38(26), 1997, pp. 4659-4662
A novel family of urea-based peptidomimetics containing beta-alanyl un
it at the core has been synthesized by a simple one-step procedure. So
lid state structures of some representative examples have showm self-a
ssembly into highly ordered extended hydrogen-bonded chains and ribbon
s with modest NLO activity. (C) 1997 Elsevier Science Ltd.
