A low temperature, vinylboronate ester-mediated, iterative cross-coupling approach to xanthomonadin polyenyl pigment analogues
Madden, Katrina S.,Knowles, Jonathan P.,Whiting, Andrew
, (2019)
Approaches to the polyene natural product xanthomonadin, an octaenyl electron-deficient bacterial photoprotective agent, and its debromo analogue, were developed. These involved the iterative cross-coupling of multiple C2-fragments, using a vinylboronate

Paragraph 0027-0030, (2021/03/13)
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.
