Labile γ-glutamaldehydic acid (1) was first converted to tryptophan via its phenylhydrazone; no racemization occurred during the reaction. The stability of 1 was shown to be remarkably enhanced in the presence of additives.
The 1-azabicyclo[3.1.0]hexane ring is a key moiety in natural products for biologicalactivities against bacteria, fungi, and tumor through DNA alkylation. Ficellomycin is a dipeptide that consists of L-valine and a non-proteinogenic amino acid with the 1-azabicyclo[3.1.0]hexane ring structure. Although the biosynthetic gene cluster of ficellomycin has been identified, the biosynthetic pathway currently
