Short and efficient synthesis of diazabicycloalkane dipeptide mimics

10.1055/s-2002-34901

The research presents a short and efficient synthetic route to enantiomerically pure diazabicycloalkane dipeptide mimics. The key step involves an oxidative cleavage of azabicycloalkene precursors, which are synthesized in enantiomerically pure form via an aza-Diels–Alder reaction. A range of diazabicycloalkanes with different amino acid side chains have been synthesized, and their structures elucidated by NMR analysis. The synthesis starts from readily available azabicycloalkene, which is converted into various intermediates. Key chemicals used in the research include K2OsO2(OH)4 and K3Fe(CN)6 for the bishydroxylation step, DCC and HOBt for peptide coupling, and NaIO4 for the oxidative cleavage of diols to form the final diazabicycloalkane dipeptide mimics. The resulting compounds are versatile precursors for dipeptide mimics and can be further modified for various applications, such as serving as modular ligands for cancer cell-specific enzymes.
