electrochemical method has been developed for selective benzylic iodination of methylarenes. The reactions feature the first use of N-hydroxyphthalimide as an electrochemical mediator for C-H oxidation to nonoxygenated products. The method provides the basis for direct (in situ) or sequential benzylation of diverse nucleophiles using methylarenes as the alkylating agent. The hydrogen-atom transfer mechanism for

Quick Access to Nucleobase-Modified Phosphoramidites for the Synthesis of Oligoribonucleotides Containing Post-Transcriptional Modifications and Epitranscriptomic Marks
nucleobases of commercially available nucleoside phosphoramidites. This method involves the deprotonation of amide groups under phase-transfer conditions and subsequent reaction with electrophilic molecules such as alkyl halides or organic isocyanates. Using this approach, we obtained 10 different classes of modified nucleoside phosphoramidites suitable for the synthesis of oligonucleotides, including several
