Autor: Roman A. Novikov, Denis D. Borisov, Dmitry A. Denisov, Maxim A. Novikov, Konstantin V. Potapov, Yaroslav V. Tkachev, Yury V. Tomilov
Publikováno v: Nature Communications, Vol 15, Iss 1, Pp 1-11 (2024)
Abstract The direct C–H activation of inert C(sp3)–H bonds in a hydrocarbon chain has been a very attractive target in organic synthesis for many decades. Among all the variety of processes, those driven by vinyl carbocations are quite scarce thu

Autor: Konstantin V. Potapov, Roman A. Novikov, Maxim A. Novikov, Pavel N. Solyev, Yury V. Tomilov, Sergey N. Kochetkov, Alexander A. Makarov, Vladimir A. Mitkevich
Publikováno v: Molecules, Vol 28, Iss 8, p 3568 (2023)
Bacterial cystathionine γ-lyase (bCSE) is the main producer of H2S in pathogenic bacteria such as Staphylococcus aureus, Pseudomonas aeruginosa, etc. The suppression of bCSE activity considerably enhances the sensitivity of bacteria to antibiotics.

'Cyclopropanation of Cyclopropanes': GaCl3-Mediated Ionic Cyclopropanation of Donor–Acceptor Cyclopropanes with Diazo Esters as a Route to Tetrasubstituted Activated Cyclopropanes
Autor: I. A. Borisova, Roman A. Novikov, Yury V. Tomilov, Daria-Maria V. Ratova, Anna V. Tarasova, Konstantin V. Potapov
Publikováno v: The Journal of Organic Chemistry. 86:4567-4579
A new ionic cyclopropanation process involving the addition of diazo esters to donor-acceptor cyclopropanes (DAC) activated by GaCl3 has been developed. The reactions occur via 1,2-zwitterionic gallium complexes with elimination of nitrogen in all ca
