Compound: 6-Chloropyridine-2-boronic Acid, is researched, Molecular C5H5BClNO2, CAS is 652148-90-8, about Large screening of DNA-compatible reaction conditions for Suzuki and Sonogashira cross-coupling reactions and for reverse amide bond formation. Author is Favalli, Nicholas; Bassi, Gabriele; Bianchi, Davide; Scheuermann, Jorg; Neri, Dario.

Progress in DNA-encoded chem. library synthesis and screening crucially relies on the availability of DNA-compatible reactions, which proceed with high yields and excellent purity for a large number of possible building blocks. In the past, exptl. conditions have been presented for the execution of Suzuki and Sonogashira cross-coupling reactions on-DNA. In this article, our aim was to optimize Suzuki and Sonogashira reactions, comparing our results to previously published procedures. We have tested the performance of improved conditions using 606 building blocks (including boronic acids, pinacol boranes and terminal alkynes), achieving >70% conversion for 84% of the tested mols. Moreover, we describe efficient exptl. conditions for the on-DNA synthesis of amide bonds, starting from DNA derivatives carrying a carboxylic acid moiety and 300 primary, secondary and aromatic amines, as amide bonds are frequently found in DNA-encoded chem. libraries thanks to their excellent DNA compatibility.
