Ammonia-borane serves as an efficient substoichiometric (10%) precatalyst for the direct amidation of both aromatic and aliphatic carboxylic acids. In situ generation of amine-boranes precedes the amidation and, unlike the amidation with stoichiometric amine-boranes, this process is facile with 1 equiv of the acid. This methodology has high functional group tolerance and chromatography-free purification but is not amenable for esterification. The latter feature has been exploited to prepare hydroxyl- and thiol-containing amides.
Reduction with tris(2-carboxyethyl)phosphine (TCEP) enables the use of an S-sulphonate protecting group for thiol-mediated bioconjugation

Herein, we demonstrate the effectiveness of the water-friendly S-sulphonate group as an alternative to traditional thiol protecting groups for subsequent deprotection-bioconjugation reactions, under conditions that are compatible with the use of biochemic
