Osmium Catalyzed Oxidative Cyclization

Timothy Donohoe and co-workers at the University of Oxford have published in Synlett on an osmium catalyzed oxidative cyclization of a vinyl silane tethered with an alcohol to form substituted tetrahydrofurans.

Osmium Catalyzed Hydroalkoxylation

With all of the hype of the typical transition metals for hydryalkoxylation reactions such as platinum, gold, and silver, people seem to forget about the other transition metals.  Carlos Saa and co-workers from Universidad de Santiago de Compostela in Spain have recently reported in ACIEE on an osmium catalyzed hydroalkoxylation reaction to lead to benzoxepine structures.
