A diastereoselective synthesis of pseudopeptidic hydantoins by an Ugi/cyclization/Ugi sequence
摘要:
A diastereoselective synthesis of helix-forming pseudopeptidic hydantoins by an Ugi 4CC/cyclization/reduction/Ugi 4CC sequence of reactions, giving mainly the L-adduct when benzoic acids were used, is described. (C) 2012 Elsevier Ltd. All rights reserved.
