Larsson, Rikard,Sterner, Olov,Johansson, Martin
, p. 657 - 660 (2009)
(Figure Presented) A concise biomimetic approach toward transtaganolides C and D involving an Ireland-Claisen rearrangement/intramolecular Diels-Alder reaction sequence suggesting the involvement of pericyclic reactions in the biosynthesis of these biologically active plant metabolites is presented. A final coupling reaction establishes the carbon framework of the transtaganolides.
Gold (I/III)-Catalyzed Trifluoromethylthiolation and Trifluoromethylselenolation of Organohalides

The first C?SCF3/SeCF3 cross-coupling reactions using gold redox catalysis [(MeDalphos)AuCl], AgSCF3 or Me4NSeCF3, and organohalides as substrates are reported. The new methodology enables a one-stop shop synthesis of aryl/alkenyl/alkynyl trifluoromethylthio- and selenoethers with a broad substrate scope (>60 examples with up to 97 % isolated yield). The method is scalable, and its robustness is evidenced by the late-stage functionalization of various bioactive molecules, which makes this reaction an attractive alternative in the synthesis of trifluoromethylthio- and selenoethers for pharmaceutical and agrochemical research and development.

The invention provides a compound, a preparation method thereof and an application of the compound in preparation of drugs for treating small cell lung cancer. The structural formula of the compound is shown in the specification, and the compound generates a synergistic effect on small cell lung cancer tumor cells by blocking the activity of PARP and/or XPO1 protein. Researches show that the compound provided by the invention can effectively inhibit proliferation of small cell lung cancer cells in vivo and in vitro, and can be applied to drugs for treating small cell lung cancer.
Enantioselective Synthesis of α-Chiral Propargylic Silanes by Copper-Catalyzed 1,4-Selective Addition of Silicon Nucleophiles to Enyne-Type α,β,γ,δ-Unsaturated Acceptors

A copper-catalyzed deconjugative addition of silicon nucleophiles to a broad range of enyne-type α,β,γ,δ-unsaturated acceptors with high enantiocontrol is reported. The method is 1,4-selective with hardly any formation of the 1,6-adduct. The double-bond geometry is shown to be critical for achieving this chemoselectivity: exclusive 1,4-addition for E and predominant 1,6-addition for Z. By this, E-configured enynoates, enynamides, and enynones have been converted to the corresponding α-chiral propargylic silanes with excellent enantiomeric excesses.
