On the Use of Five-Membered Heterocycles in Peptide Chemistry

Article abstract of DOI:10.1055/s-1985-31329

N-Acyl derivatives of 2-benzoxazolethiol, 2-benzothiazolethiol and 2-benzimidazolethiol are proposed for use both as efficient acylating agents for the synthesis of N-benzyloxycarbonyl and N-fluorenylmethyloxycarbonyl amino acid derivatives and as activated amides for the synthesis of peptides.
