Chemical constituents of the soft corals Sinularia vanderlandi and Sinularia gravis from the coast of Madagascar

Rahelivao M.; Gruner M.; Lübken T.; Islamov D.; Kataeva O.; Andriamanantoanina H.; Bauer I.; Knölker H. (2002)

© 2016 The Royal Society of Chemistry. The crude extracts of the Madagascan soft corals Sinularia vanderlandi and Sinularia gravis (Alcyoniidae) showed activity against Plasmodium falciparum which led us to study their ...

Rahelivao M.; Gruner M.; Lübken T.; Islamov D.; Kataeva O.; Andriamanantoanina H.; Bauer I.; Knölker H. (2016)

© 2016 The Royal Society of Chemistry.The crude extracts of the Madagascan soft corals Sinularia vanderlandi and Sinularia gravis (Alcyoniidae) showed activity against Plasmodium falciparum which led us to study their ...
Enantioselective Total Synthesis and Assignment of the Absolute Configuration of the Furo[3,2- a]carbazole Alkaloid Furoclausine-B

Spindler B.; Kataeva O.; Knölker H. (2018)

© Copyright 2018 American Chemical Society. We describe the first enantioselective total synthesis and the assignment of the absolute configuration of the furo[3,2-a]carbazole alkaloid furoclausine-B. As key steps for our ...
First Total Synthesis of 7-Isovaleryloxy-8-methoxygirinimbine

Brütting C.; Schmidt A.; Kataeva O.; Knölker H. (2018)

© Georg Thieme Verlag Stuttgart New York Synthesis. We describe the first total synthesis of the pyrano[3,2- a ]carbazole alkaloid 7-isovaleryloxy-8-methoxygirinimbine, using a palladium(II)-catalyzed double C-H-bond ...
First Total Synthesis of the Cytotoxic Carbazole Alkaloid Excavatine-A and Regioselective Annulation to Pyrano[2,3-a]carbazoles and [1,4]Oxazepino[2,3,4-jk]carbazoles

Brütting C.; Kataeva O.; Schmidt A.; Knölker H. (2017)

© 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim We describe the first total synthesis of the cytotoxic carbazole alkaloid excavatine-A. The carbazole framework was constructed through double C–H bond activation of a ...
Isolation and structure elucidation of natural products of three soft corals and a sponge from the coast of Madagascar

Rahelivao M.; Lübken T.; Gruner M.; Kataeva O.; Ralambondrahety R.; Andriamanantoanina H.; Checinski M.; Bauer I.; Knölker H. (2017)

© The Royal Society of Chemistry.We investigated the three soft corals Sarcophyton stellatum, Capnella fungiformis and Lobophytum crassum and the sponge Pseudoceratina arabica, which have been collected at the coast of ...
Synthesis of Euchrestifoline Using Iron- and Palladium-Catalyzed C–H Bond Activations

Puls F.; Kataeva O.; Knölker H. (2018)

© 2018 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim We describe a short and efficient synthetic route to euchrestifoline. Key steps of our approach are the iron(III)-catalyzed Wacker-type oxidation of a chromene derivative ...
Synthesis of Tetranuclear Palladium(II) Complexes and Their Catalytic Activity for Cross-Coupling Reactions

Puls F.; Richter N.; Kataeva O.; Knölker H. (2017)

© 2017 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim We have developed a short and simple synthesis of tetranuclear palladium(II) complexes that have been structurally confirmed by X-ray analysis. These complexes were formed ...
