of benzyl propargyl ethers react with a gold(I) catalyst to furnish variously substituted allenes via a 1,5-hydride shift/fragmentation sequence. This transformation is rapid and practical. It can be performed under very mild conditions (room temperature or 60 degrees C) using terminal as well as substituted alkyne substrates bearing a primary, secondary, or tertiary benzyl ether group. The allenes

rhodium-catalyzed C–H functionalization-based intermolecular allylation of indoles with trisubstituted allenes has been developed. This synthetic process proceeds with an excellent regioselectivity, Z-selectivity, high efficiency of chirality transfer, and a wide tolerance of reactive functional groups under mild conditions.
