Abstract
Thiohydantoin represents a significant class of biologically active privileged heterocyclic scaffolds. Herein, we present a convenient and robust DNA-compatible method for constructing a thiohydantoin-focused DNA-encoded library. This reaction can be applied to a wide variety of isothiocyanate partners, arylamine feedstocks, and diverse α-amine acid derivatives, exhibiting excellent conversions, high functional group tolerance, and preservation of DNA tag integrity. Our method allows for easy access to a valuable three-cycle thiohydantoin-focused DNA-encoded library.

Abstract
On-DNA carboxylic acids are important synthetic intermediates in the synthesis of DNA-encoded library (DEL) structures. Herein, we report an oxoammonium salt-mediated, room temperature, solution-phase oxidation of DNA-linked primary alcohols into carboxylic acids. This method exhibits a wide substrate scope, encompassing aliphatic, benzylic, and heterobenzylic alcohols, and is compatible with DEL encoding strategies. This advancement facilitates a DEL strategy to utilize unprotected alcohols as inert, masked carboxylic acids and enables access to noncommercial bifunctional carboxyl intermediates to enhance the accessible chemical diversity within DELs.

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
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
Over the past three decades, DNA-encoded library (DEL) technologies have become one of the most relevant strategies for hit-finding. Recent advances in synthetic methodologies for DNA-encoded libraries rendered the increased chemical space available, but it is unknown how every variety of chemistry affects DNA's integrity. Available assays to quantify DNA damage are restricted to electrophoresis, ligation efficiency, and mostly qPCR quantification and sequencing, which may contain predisposition and inconsistency. We developed an external standard method through LC-MS analysis to accurately quantify DNA damage throughout the chemical transformations. An assessment was conducted on on-DNA chemical reactions that are frequently employed in DEL synthesis, and these results were compared to traditional qPCR measurements. Our study provides a simple, practicable, and accurate measurement for DNA degradation during DEL synthesis. Our finding reveals substantial disagreement among the usual DNA-damaging assessment methods, which have been largely neglected so far.

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
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
1-Iodoalkynes and 1,3-diynes are versatile chemical intermediates and pharmaceutically valuable ingredients. In this study, copper mediated on-DNA alkyne iodination and Cadiot-Chodkiewicz coupling are developed for the first time. This generates diverse, systematic, and unprecedented topographic structural features, which could be invaluable as molecular recognition agents for drug discovery in DEL screening.
