Construction of 1,5-Enynes by Stereospecific Pd-Catalyzed Allyl–Propargyl Cross-Couplings
摘要:
The palladium-catalyzed cross-coupling of chiral propargyl acetates and allyl boronates delivers chiral 1,5-enynes with excellent levels of chirality transfer and can be applied across a broad range of substrates.

Going (anti)viral: The first total synthesis of the antiviral (+)‐schisanwilsonene A has been completed using a fully stereoselective tandem cyclization/1,5‐migration/intermolecular cyclopropanation. The key reaction sequence is catalyzed by gold.
