C-H activation is a powerful strategy for forming C-C bonds without the need for prefunctionalization. In this paper, we present a general, direct, and regioselective palladium-catalyzed functionalization of a phosphorus heterocycle, 2-phenyl-1H-isop

Benign synthesis of therapeutic agents: domino synthesis of unsymmetrical 1,4-diaryl-1,4-dihydropyridines in the ball-mill

Autor: Cristina Blazquez-Barbadillo, Juan Francisco González, Andrea Porcheddu, David Virieux, José Carlos Menéndez, Evelina Colacino

Publikováno v: Green Chemistry Letters and Reviews, Vol 15, Iss 4, Pp 881-892 (2022)

The solvent-free preparation of unsymmetrical N-aryl-5,6-unsubstituted-1,4-dihydropyridines (DHPs) by ball-milling was investigated. Three different mechanochemical domino reactions (one-pot/one step or stepwise) were studied, the process parameters

Access to 2-Fluorinated Aziridine-2-phosphonates from α,α-Halofluorinated β-Iminophosphonates—Spectroscopic and Theoretical Studies

Autor: Mateusz Klarek, Tomasz Siodła, Tahar Ayad, David Virieux, Magdalena Rapp

Publikováno v: Molecules, Vol 28, Iss 14, p 5579 (2023)

The efficient one-pot halofluorination of a β-enaminophosphonate/β-iminophosphonate tautomeric mixture resulting in α,α-halofluorinated β-iminophosphonates is reported. Subsequent imine reduction gave the corresponding β-aminophosphonates as a

Fluorinated phosphonate analogues of phenylalanine: Synthesis, X-ray and DFT studies

Autor: Joanna Kwiczak-Yiğitbaşı, Jean-Luc Pirat, David Virieux, Jean-Noël Volle, Agnieszka Janiak, Marcin Hoffmann, Donata Pluskota-Karwatka

Publikováno v: Arabian Journal of Chemistry, Vol 13, Iss 1, Pp 2384-2399 (2020)

Due to their biological activity and structural analogy to corresponding α-amino acids, α-aminophosphonates and their fluorinated derivatives provide an important source for drug discovery. Therefore convenient access to this class of compounds is
