Copper-Catalyzed Enantioselective Allyl–Allyl Cross-Coupling [PDF]
Journal of the American Chemical Society, 2013 A Cu(I)-phosphoramidite-based catalytic system that allows asymmetric allyl-allyl cross-coupling with high enantioselectivity is reported. This transformation tolerates a large variety of functionalized substrates. The versatility of this new reaction is illustrated in the catalytic asymmetric synthesis of the Martinelline alkaloids chromene derivative
