1-(叔丁氧基羰基)-2-甲基氮丙啶-2-羧酸 | (R,S)-methyl N-(t-butoxycarbonyl)aziridine-2-carboxylate | 181212-90-8 | C9H15NO4 | 201.222 |
Aziridine derivatives involved in nucleophilic ring-opening reactions have attracted great interest, since they allow the preparation of biologically active molecules. A chemoselective and mild procedure to convert a peptide cysteine residue into lanthionine via S-alkylation on aziridine substrates is presented in this paper. The procedure relies on a post-synthetic protocol promoted by molecular sieves to prepare lanthionine-containing peptides and is assisted by microwave irradiation. In addition, it represents a valuable alternative to the stepwise approach, in which the lanthionine precursor is incorporated into peptides as a building block.
