BAC to the future: Boronic acid catalysis (BAC) was applied to the direct activation of alcohols leading to the preparation of carbocycles (see scheme), benzofurans, tetrahydrofurans, pyrrolidines, pyrans, piperidines, and various polycyclic compounds. The reactions proceed under mild conditions that circumvent the use of reactive leaving groups like halides. Copyright

Treatment of (E)-6-phenyl-5-hexenyl carbamates with s-BuLi/(-)-sparteine is shown to afford the trans-1,2-disubstituted cyclopentane derivatives in high % ee, along with the bicyclo[3.1.0]hexanes (bicyclization products).

Lipase-catalyzed enantioselective lactonization of racemic methyl 6-phenyl-4-hydroxy-5-hexynoate worked well to afford (R)-6-phenyl-5-hexyn-4-olide (42 percent yield, 81 percent e.e.).The e.e. of the product was enhanced to 97 percent by the repetition of
