Visual detection of formaldehyde by highly selective fluorophore labeling via gold(III) complex-mediated three-component coupling reaction.

A novel method for visual detection of formaldehyde with excellent selectivity via a gold(iii) complex-mediated three-component coupling reaction of resin-linked sterically bulky amines and fluorescent alkynes has been developed.

N-Terminal α-amino group modification of peptides by an oxime formation-exchange reaction sequence.

A site-specific and efficient method for N-terminal modification of peptides using oxone for selective oxidation of N-terminal α-amino groups of peptides to oximes followed by transoximation with O-substituted hydroxylamines has been developed.
