reactions between biological thiols and endocyclic olefinicmaleimides are extensively used for site‐specific bioconjugation. The resulting thio‐succinimidyl linkages, however, lack stability because of their susceptibility to thiol exchange. Reported herein is that in contrast to their endocyclic counterparts, exocyclicolefinicmaleimides form highly stable thio‐Michael adducts which resist thiol exchange
