from native non‐engineered monoclonal antibodiesthrough a simple one‐pot reduction and alkylation. Ethynylphosphonamidates can be easily substituted with hydrophilic residues, giving rise to electrophilic labeling reagents with tunable solubility properties. We demonstrate that ethynylphosphonamidate‐linked ADCs have excellent properties for next‐generation antibody therapeutics in terms of serum stability

Disclosed are novel conjugates and processes for the preparation thereof. A process tor the preparation of alkene- or alkyne-phosphonamidates comprises the steps of (I) reacting a compound of formula (III), with an azide of formula (IV), to prepare a compound of formula (V), reacting a compound of formula (V) with a thiol-containing molecule of formula (VI), resulting in a compound of formula (VII).
