To access mimics of peptide β-strands (1), scalemic 3,5,5-trisubstituted pyrrolin-4-ones bearing the tyrosine, serine, and lysine side-chains have been generated via cyclization of metalated imino esters and deprotection. The functionalized imino esters were prepared by asymmetric alkylation of a common oxazolidinone precursor (2) derived from L-rhenylglycine.
