Chiral N-beta-Fmoc amino alkyl isonitriles were employed in Ugi multi component reactions (Ugi 4C-3CR) to obtain functionalized beta-lactam peptidomimetics with L-aspartic acid alpha-methyl ester/peptide ester and organic aldehydes. The reactions were carried out in MeOH. Thirteen Ugi products have been prepared in good to moderate yields with good diastereoselectivities. (C) 2011 Elsevier Ltd. All rights reserved.
