  Synthesis of Optically Active 2-Alkyl-3,4-iminobutanoic Acids. β-Amino Acids Containing an Aziridine Heterocycle

  摘要：

  All four stereoisomers of 2-alkyl-3,4-iminobutanoic acid, a novel class of beta -amino acids bearing a chemically versatile aziridine ring, were synthesized starting with aspartic acid. The synthetic strategy involves the introduction of an alkyl group at the beta -position of fully protected optically active aspartic acid followed by the construction of an aziridine ring making use of the alpha -carboxylate and alpha -amino groups. The alpha -carboxylate was reduced to the corresponding alcohol, which was then subjected to cyclization to form an aziridine ring with the N-protected amino group. Removal of the protection groups yielded the target compounds.
