Concise synthesis of α-alkyl α-amino acids and their incorporation into peptides viaβ-lactam-derived α-amino acid N-carboxy anhydrides
摘要:
alpha-Hydroxy beta-lactams in which C-4 exists as a quaternary carbon are transformed in a single one-pot operation into alpha,alpha-dialkyl alpha-amino acid N-carboxy anhydrides providing a new approach to conformationally restricted peptide segments from non alpha-amino acid precursors.
