A Michaelis-Arbuzov-Type Pathway to a Protected 2'-Deoxy-2'-Selenomethyl-Adenosine-3',5'-Phosphoroselenolate Guanosine Dinucleotide for Use in Modified m7G Cap Synthesis. [PDF]

open access: yesChemistry
Here we report a synthesis of the dinucleotide 4 for a projected future total synthesis of the m7G cap 1. Highlights of the route include: 1) a 3ʹ‐H‐phosphonate/5ʹ‐selenocyanate Michaelis‐Arbuzov coupling to forge the 3ʹ,5ʹ‐phosphoroselenolate; 2) an Amosova reductive selenomethylation to install the 2ʹ‐SeMe; 3) a solid CPR II 5ʹ‐O‐phosphitylation; and

Self-Assembly of a Customizable Library of Nickel Trifluoromethylation Catalysts via Selective C─F and C─O Bond Cleavage. [PDF]

open access: yesAngew Chem Int Ed Engl
Carbatranes and anionic pincer ligands were self‐assembled via one‐pot C─F or C─O bond cleavage and the formation of C─O, C─N, or C─C bonds, forming ligand architectures inaccessible by common synthetic methods. This approach allowed to build a customizable library of nickel catalysts for light‐induced C─H bond trifluoromethylation.

Structures of a Phosphoryl Derivative of 4-Allyl-2,4-dihydro-3H-1,2,4-triazole-3-thione: An Illustrative Example of Conformational Polymorphism

open access: yesCrystals, 2021
Two polymorphic forms of a conformationally flexible molecule, 5-[(Diphenylphosphoryl)methyl]-4-(prop-2-en-1-yl)-2,4-dihydro-3H-1,2,4-triazole-3-thione, were obtained by crystallization and characterized by X-ray diffraction analysis and differential ...

Thymine-Modified Nanocarrier for Doxorubicin Delivery in Glioblastoma Cells

open access: yesMolecules, 2023
Brain tumor glioblastoma is one of the worst types of cancer. The blood–brain barrier prevents drugs from reaching brain cells and shields glioblastoma from treatment.

1,2,3-Triazoles as leaving groups in SNAr–Arbuzov reactions: synthesis of C6-phosphonated purine derivatives

open access: yesBeilstein Journal of Organic Chemistry, 2021
A new method for C–N bond transformations into C–P bonds was developed using 1,2,3-triazoles as leaving groups in SNAr–Arbuzov reactions. A series of C6-phosphonated 2-triazolylpurine derivatives was synthesized for the first time, with the isolated ...

FACILITATION OF CHORUS ROLE IN A. N. ARBUZOV’S PARABLE “THE HAPPY DAYS OF AN UNHAPPY MAN” [PDF]

open access: yesPhilology. Theory & Practice, 2018
The article is devoted to the analysis of the facilitated image of the chorus and its functions in the parable “The Happy Days of an Unhappy Man”, which was written by the Soviet playwright A. N. Arbuzov in 1967. It is proved that in the play the playwright simplifies the role of the chorus, facilitates its presence on the stage.
