Abstract:Strategies for one‐pot peptide ligation enable chemists to access synthetic proteins at a high yield in a short time. Herein, we report a novel one‐pot multi‐segments ligation strategy using N‐terminal thiazolidine (Thz) peptide and a newly designed formaldehyde scavenger. Among the designed 2‐aminobenzamide‐based aldehyde scavengers, 2‐amino‐5‐methoxy‐N′,N′‐dimethylbenzohydrazide (AMDBH) can remarkably convert Thz into unprotected cysteine at pH 4.0. Furthermore, AMDBH degrades Thz at a considerably low rate … Show more
