Strategic approaches to the synthesis of pyrrolizidine and indolizidine alkaloids
Nina K. Ratmanova,Ivan A. Andreev,Alexandre V. Leontiev,Daria Momotova,Anton M. Novoselov,Olga A. Ivanova,Olga A. Ivanova,Igor V. Trushkov +7 more
TL;DR: In this paper, the principal methods for the synthesis of pyrrolizidine and indolizidine alkaloids and their unnatural analogs are described and six main "strategic" approaches in regard to a key step forming azabicyclic skeleton are identified.
Journal ArticleDOI
Protic Ionic Liquid as Reagent, Catalyst, and Solvent: 1-Methylimidazolium Thiocyanate
Ivan A. Andreev,Nina K. Ratmanova,André U. Augustin,Olga A. Ivanova,Olga A. Ivanova,Irina I. Levina,Victor N. Khrustalev,Daniel B. Werz,Igor V. Trushkov +8 more
TL;DR: In this article, the authors proposed a triple role of protic ionic liquids with nucleophilic anions: a regenerable solvent, a Bronsted acid inducing diverse transformations via general acid catalysis and a source of a nucleophile.
Journal ArticleDOI
A Structural and Stability Evaluation of Au12 from an Isolated Cluster to the Deposited Material
TL;DR: In this paper, the morphology and charged state of gold clusters play a crucial role in heterogeneous catalysis and the selection and optimization of theoretical approaches are necessary for the investigation of act...
Journal ArticleDOI
Discovery of the 2-phenyl-4,5,6,7-Tetrahydro-1H-indole as a novel anti-hepatitis C virus targeting scaffold.
Ivan A. Andreev,Dinesh Manvar,Maria Letizia Barreca,Dmitry S. Belov,Amartya Basu,Noreena L. Sweeney,Nina K. Ratmanova,Evgeny R. Lukyanenko,Giuseppe Manfroni,Violetta Cecchetti,David N. Frick,Andrea Altieri,Neerja Kaushik-Basu,Alexander V. Kurkin +13 more
TL;DR: Biochemical assays showed that derivative 39 had no effect on HCV NS5B polymerase, NS3 helicase, IRES mediated translation and selected host factors, and future work will involve both the chemical optimization and target identification of 2-phenyl-4,5,6,7-Tetrahydro-1H-indoles as new anti-HCV agents.
Journal ArticleDOI
Oxidative Dearomatization of 4,5,6,7‐Tetrahydro‐1H‐indoles Obtained by Metal‐ and Solvent‐Free Thermal 5‐endo‐dig Cyclization: The Route to Erythrina and Lycorine Alkaloids
Ivan A. Andreev,Nina K. Ratmanova,Anton M. Novoselov,Dmitry S. Belov,I. F. Seregina,Alexander V. Kurkin +5 more
TL;DR: The utility of obtained indolones as unified key precursors is demonstrated by the application of these products to the formal total syntheses of a whole pleiad of Erythrina- and Lycorine-type alkaloids.
