On the Use of Five-Membered Heterocycles in Peptide Chemistry

Romani, S.,Moroder, L.,Bovermann, G.,Wuensch, E.

, p. 738 - 742 (2007/10/02)

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.
