Stereoselective Synthesis of the I–L Fragment of the Pacific Ciguatoxins

Autor: J. Stephen Clark, Michael Popadynec

Publikováno v: Toxins, Vol 12, Iss 12, p 740 (2020)

The I–L ring system found in all the Pacific ciguatoxins has been prepared from a tricyclic precursor in a highly stereoselective manner. Subtle differences in the reactivity of the enones present in the seven- and eight-membered rings of the tricy

The Pd–benzothiazol-2-ylidene complex I was found to be a chemoselective catalyst for the Tsuji–Trost allylation of active methylene compounds carried out under neutral conditions and using carbonates as allylating agents. The proposed protocol c

Autor: Thomas, Schlatzer, Hilmar, Schröder, Melanie, Trobe, Christian, Lembacher-Fadum, Simon, Stangl, Christoph, Schlögl, Hansjörg, Weber, Rolf, Breinbauer

Publikováno v: Advanced Synthesis & Catalysis

The Pd‐catalyzed S‐allylation of thiols with stable allylcarbonate and allylacetate reagents offers several advantages over established reactions for the formation of thioethers. We could demonstrate that Pd/BIPHEPHOS is a catalyst system which a
