The identification of fast, chemoselective bond-forming reactions is one of the major contemporary challenges in chemistry. We show that chemoselective amide-formingligations of potassium acyltrifluoroborates (KATs) and O-carbamoylhydroxylamines proceed in the presence of all unprotected functional groups with a second-order rate constant of 20 M(-1) s(-1). PEG chains, lipids, biotin, and dyes were

Bioorthogonal de novo phospholipid synthesis utilizing the reactions between hydroxylamine and α-ketoacids (KAs) or potassium acyltrifluoroborates (KATs) enables the rapid formation of biomimetic membranes under physiological pH conditions, using reactant concentrations in the micromolar range. Additionally, these reactions are biocompatible and can be performed in living mammalian cells.
