cross-coupling of propargylic mesylates and Grignard reagents for the synthesis of diverse chiral allenes catalyzed by a recyclable heterogeneous nanocopper catalyst is reported. The synthetic utility of this sustainable methodology was further demonstrated by its application to the asymmetric total synthesis of 5 valuable allenic natural products.
