Abstract
DNA-encoded library (DEL) technologies enable the fast exploration of gigantic chemical space to identify ligands for the target protein of interest and have become a powerful hit finding tool for drug discovery projects. However, amenable DEL chemistry is restricted to a handful of reactions, limiting the creativity of drug hunters. Here, we describe a new on-DNA synthetic pathway to access sulfides and sulfoximines. These moieties, usually contemplated as challenging to achieve through alkylation and oxidation, can now be leveraged in routine DEL selection campaigns.

Abstract
Using a novel homologation-heterocyclization cascade, the on-DNA synthesis of benzofurans from aldehydes has been developed. The methodology, based on an innovative use of the Seyferth-Gilbert homologation, followed by a high yielding Sonogashira coupling in situ intramolecular cyclization one-pot, two-step reaction, provides a powerful and unique pathway for DNA-encoded library (DEL) synthesis of a wide array of pharmaceutically relevant benzofuran-based scaffolds.

Abstract
In DNA-encoded library synthesis, amine-substituted building blocks are prevalent. We explored isocyanide multicomponent reactions to diversify DNA-tagged amines and reported the Ugi-azide reaction with high yields and a good substrate scope. In addition, the Ugi-aza-Wittig reaction and the Ugi-4-center-3-component reaction, which used bifunctional carboxylic acids to provide lactams, were explored. Five-, six-, and seven-membered lactams were synthesized from solid support-coupled DNA-tagged amines and bifunctional building blocks, providing access to structurally diverse scaffolds.

Abstract
Here, we describe a novel method for the on-DNA synthesis of cyclic imides, an important class of molecules that includes several well-known medications. Significantly, the new method enabled on-DNA synthesis under mild conditions with high conversions and a broad functional group tolerance, utilizing ubiquitous bifunctional amines and bis-carboxylic acid, or alkyl halides, and therefore served as the linchpin for DNA encoded library (DEL) synthesis. The mechanism study of off-DNA and on-DNA chemical transformations revealed unique insights in contrast to conventional chemical transformation.

Abstract
We herein present the first application of the on-DNA Morita-Baylis-Hillman (MBH) reaction for the creation of pharmaceutically relevant targeted covalent inhibitors (TCIs) with an α-hydroxyl Michael acceptor motif. Adapting a DNA-compatible organocatalytic process, this MBH reaction for covalent selection-capable DNA encoded library (DEL) synthesis grants access to densely functionalized and versatile precursors to explore novel chemical space for molecule recognition in drug discovery. Most importantly, this methodology sheds light on potentially unexpected reaction outcomes of the MBH reaction.

Abstract
Thiophene and its substituted derivatives are a highly important class of heterocyclic compounds, with noteworthy applications in pharmaceutical ingredients. In this study, we leverage the unique reactivity of alkynes to generate thiophenes on-DNA, using a cascade iodination, Cadiot-Chodkiewicz coupling and heterocyclization. This approach, tackling on-DNA thiophene synthesis for the first time, generates diverse, and unprecedented structural and chemical features, which could be significant motifs in DEL screening as molecular recognition agents for drug discovery.

Abstract
Organophosphonic compounds are distinctive among natural products in terms of stability and mimicry. Numerous synthetic organophosphonic compounds, including pamidronic acid, fosmidromycin, and zoledronic acid, are approved drugs. DNA encoded library technology (DELT) is a well-established platform for identifying small molecule recognition to target protein of interest (POI). Therefore, it is imperative to create an efficient procedure for the on-DNA synthesis of α-hydroxy phosphonates for DEL builds.

Abstract
An efficient approach for aryl acetylene DNA-encoded library (DEL) synthesis was developed in this study by transition-metal-mediated inverse Sonogashira reaction of 1-iodoalkyne with boronic acid under ambient conditions, with moderate to excellent conversions and broad substrate adaptability for the first time. Compared to palladium-phosphine, copper iodide performed better in the on-DNA inverse Sonogashira reaction. Interestingly, substrate diversity can be enhanced by first interrogating coupling reagents under copper-promoted conditions, and then revalidating them under palladium-facilitated conditions for those reagents which failed under the former. This complementary validation strategy is particularly well-fitted to any DEL validation studies.

Abstract
Through a modified Kinugasa reaction, a novel method of amidation on terminal oligo alkyne conjugates by copper-promoted oxidation with nitrones has been developed. Unprotected bifunctional carboxylic acid-amine reagents can be transformed directly to the respective amide products under these edited Kinugasa reaction conditions. 3-Cycle DNA-encoded libraries (DELs) can be built in three steps of chemical conversion.
