N-methyl-N-nosyl-α-aminoacyldiazomethanes provides the corresponding N-methyl-N-nosyl-β3-amino acids with total retention of the chiral configuration of the starting α-amino acids. No epimerization of the chiral carbon atom is observed also when N-methyl-N-nosyl-β3-amino acids are transformed into chlorides and coupled with α-amino acid methyl esters to achieve model scaffolds for biologically important modified peptides
