Abstract
A simple, reliable, and efficient method for the gram-scale chemical synthesis of pyrimidine nucleosides functionalized with C5-carboxyl, nitrile, ester, amide, or amidine, starting from unprotected uridine and cytidine, is described. The protocol involves the synthesis of 5-trifluoromethyluridine and 5-trifluoromethylcytidine with Langlois reagent (CF3 SO2 Na) in the presence of tert-butyl hydroperoxide and subsequent transformation of the CF3 group to the C5-C 'carbon substituents' under alkaline conditions. © 2024 Wiley Periodicals LLC. Basic Protocol 1: Synthesis and characterization of 5-trifluoromethyluridine (5-CF3 U) and 5-trifluoromethylcytidine (5-CF3 C) Basic Protocol 2: Conversion of 5-CF3 U and 5-CF3 C to several C5-substituted ribonucleosides.

Abstract
C5-substituted pyrimidine nucleosides are an important class of molecules that have practical use as biological probes and pharmaceuticals. Herein we report an operationally simple protocol for C5-functionalization of uridine and cytidine via transformation of underexploited 5-trifluoromethyluridine or 5-trifluoromethylcytidine, respectively. The unique reactivity of the CF3 group in the aromatic ring allowed the direct incorporation of several distinct C5-C "carbon substituents": carboxyl, nitrile, ester, amide, and amidine.

RSC Chem Biol 2022; 3:1069-1075.

Abstract
Homologues of natural epigenetic pyrimidine nucleosides and nucleotides were designed and synthesized. They included 5-ethyl-, 5-propyl-, 5-(1-hydroxyethyl)-, 5-(1-hydroxypropyl)- and 5-acetyl- and 5-propionylcytosine and -uracil 2′-deoxyribonucleosides and their corresponding 5′-O-triphosphates (dNXTPs). The epimers of 5-(1-hydroxyethyl)- and 5-(1-hydroxypropyl)pyrimidine nucleosides were separated and their absolute configuration was determined by a combination of X-ray and NMR analysis. The modified dNXTPs were used as substrates for PCR synthesis of modified DNA templates used for the study of transcription with bacterial RNA polymerase. Fundamental differences in transcription efficiency were observed, depending on the various modifications. The most notable effects included pronounced stimulation of transcription from 5-ethyluracil-bearing templates (200% transcription yield compared to natural thymine) and an enhancing effect of 5-acetylcytosine versus inhibiting effect of 5-acetyluracil. In summary, these results reveal that RNA polymerase copes with dramatically altered DNA structure and suggest that these nucleobases could potentially play roles as artificial epigenetic DNA nucleobases. Nucleotides derived from homologues of epigenetic pyrimidine bases were prepared and used for polymerase synthesis of modified DNA templates. Interesting effects of the substituents on PCR and transcription have been observed.![]()

Abstract
Recent studies have indicated that 5-methylcytosine (5mC) residues in DNA can be oxidized and potentially deaminated to the corresponding thymine analogs. Some of these oxidative DNA damages have been implicated as new epigenetic markers that could have profound influences on chromatin function as well as disease pathology. In response to oxidative damage, the cells have a complex network of repair systems that recognize, remove and rebuild the lesions. However, how the modified nucleobases are detected and repaired remains elusive, largely due to the limited availability of synthetic oligodeoxynucleotides (ODNs) containing these novel DNA modifications. A concise and divergent synthetic strategy to 5mC derivatives has been developed. These derivatives were further elaborated to the corresponding phosphoramidites to enable the site-specific incorporation of modified nucleobases into ODNs using standard solid-phase DNA synthesis. The synthetic methodology, along with the panel of ODNs, is of great value to investigate the biological functions of epigenetically important nucleobases, and to elucidate the diversity in chemical lesion repair.

Abstract
This review summarizes the state of knowledge on the chemical methods of C(5)-modifications of uridine and cytidine derivatives and may serve as a useful tool for synthetic chemists to choose an appropriate reaction protocol. The synthesis of 5-substituted uracil derivatives is gaining an increasing interest because of their possible applications in medicine and pharmacy. Modifications at the C(5) position of pyrimidine nucleosides can enhance their biostability, bioavailability or(and) biological activity. Among the C(5)-modified nucleosides, 5-halopyrimidines exhibit anticancer, antiviral, radio- and photosensitizing properties. Besides 5-halo-substituted derivatives, there are other examples of nucleosides with confirmed biological activity containing a C–C bond at the C(5) position in the pyrimidine ring. In recent decades, scientists have achieved great progress in the field of cross-coupling reactions. Among them, nickel-catalyzed processes provide a broad spectrum of synthetic methods that are based on less toxic and cheaper starting materials. This review summarizes the synthetic approaches based on the coupling or halogenation reactions, which enable 5-substituted pyrimidine nucleosides to be obtained. Moreover, the importance of the systems considered for medicine and pharmacy is briefly discussed.
The bibliography includes 197 references.

Abstract
This unit describes procedures for preparation of two phosphoramidite building blocks III and IV, both containing a TBDMS as 5-CH(2)OH-protecting group. Phosphoramidites III and IV allow efficient incorporation of 5-hmC into DNA and a "one-step" deprotection procedure to cleanly remove all the protecting groups. A "two-step" deprotection strategy is compatible with ultramild DNA synthesis, which enables the synthesis of 5 hmC-containing DNA with additional modifications. Methods are also presented for their incorporation into oligonucleotides by solid-phase synthesis, subsequent deprotection, and HPLC analysis.

Abstract
5-Hydroxymethylcytosine (5-hmC) is a newly discovered DNA base modification in mammalian genomic DNA that is proposed to be a major epigenetic mark. We report here the syntheses of two new versions of phosphoramidites III and IV from 5-iodo-2'-deoxyuridine in 18% and 32% overall yields, respectively, with TBDMS as the 5-hydroxyl protecting group. Phosphoramidites III and IV allow efficient incorporation of 5-hmC into DNA and a "one-step" deprotection procedure to cleanly remove all the protecting groups. A "two-step" deprotection strategy is compatible with ultramild DNA synthesis, which enables the synthesis of 5hmC-containing DNA with additional modifications.

Abstract
A straightforward, efficient method for the synthesis of 5-formyl-2'-deoxyuridine (dfU) and solid-phase synthesis of oligodeoxynucleotides containing dfU using a phosphoramidite method are described. The synthesis of dfU is achieved by oxidation of the 5-methyl group in thymidine derivatives. However, incorporation of the dfU 3'-O-phosphoramidite into oligodeoxynucleotides proceeds in low yield, due to instability of the 5-formyl group under conditions used for automated DNA synthesis. Therefore, oligodeoxynucleotides containing a 5-(1,2-dihydroxyethyl)uracil derivative are first prepared and finally oxidized by periodate to give the desired oligodeoxynucleotides containing 5-formyluracil.

Abstract
Stille coupling under standard carbonylative conditions proceeds in poor yield when using hindered alkenylstannane and enol triflate partners. The inclusion of 35 mol % CuI or CuBr significantly improves the efficiency of the coupling, providing a variety of complex 1,4-dien-3-ones in good to excellent yield.

Preparation of 2 was facilitated by in situ transient O4-trimethylsilyl protection during alkynylation which suppressed secondary cyclization of the coupling adduct.

Abstract
Two nucleoside triphosphates, a pyrimidine modified with an ammonium functionality and a purine modified with an imidazolyl functionality are compatible with all conditions for a combinatorial selection of nucleic-acid catalysts. We believe that this work is the first to demonstrate the potential for using not one but two modified nucleotides in tandem. The potential for an enriched catalytic repertoire is envisioned.

Abstract
In vitro selection techniques provide a means of isolating nucleic acid ligands for binding to particular protein targets. Although most aptamers have quite high affinities for their target proteins, it has been shown that post-SELEX modification can result in further enhancement of binding affinity, as well as other desired properties. This has led to the current development of a more systematic approach to aptamer optimization using a combinatorial screening methodology.
