A gold(I) N-heterocyclic carbene complex catalyzes the intermolecular hydration of allenes to form allylic alcohols in modest yield with selective delivery of water to the terminal carbon atoms of the allenyl moiety.

actams via the Pd(II)-catalyzed cyclization of acyclic N-allylic 2-alkynamides via halopalladation, intramolecular olefin insertion, and beta-heteroatom elimination was developed. The reaction is less influenced by the leaving group and the concentration of the halide ions in comparison with the cyclization of acyclic alkynoates. The total syntheses of (+/-)-isocynodine and (+/-)-isocynometrine were

Olefin cross-metathesis couples two alkenes to form complex molecules and has been widely used in solution-phase organic synthesis. However, this powerful method has rarely been used in solid-phase organic synthesis. Herein we report that olefin cross-metathesis is a synthetically viable method particularly when a traceless longer linker is inserted between solid support and reacting olefins.
