title: Regio- and enantioselective cobalt-catalyzed reductive [3+2] cycloaddition reaction of alkynes with cyclic enones: a route to bicyclic tertiary alcohols.
abstract: Round and round: An unusual cobalt-catalyzed regio- and enantioselective reductive [3+2] cycloaddition of cyclic enones with alkynes affording bicyclic tertiary alcohols is described. A possible mechanism involving the formation of a cobaltacyclopentene intermediate is proposed.
