摘要
While DNA-encoded macrocyclic libraries have gained substantialattention and several hit compounds have been identified from DNA-encodedlibrary technology, efficient on-DNA macrocyclic methods are alsorequired to construct DNA-linked libraries with a high degree of cyclizationand DNA integrity. In this paper, we reported a set of on-DNA methodologies,including the use of an OPA-mediated three-component cyclization withnative handles of amino acids and photoredox chemistries. These chemistriesproceed smoothly under mild conditions in good to excellent conversions,successfully generating novel isoindole, isoindoline, indazolone,and bicyclic scaffolds.
