摘要：

Tying up loose ends: The reaction of bisallenes tethered with N-(p-tolylsulfonamide) in the presence of a cationic gold N-heterocyclic carbene catalyst gave new cycloisomerization products, 6,7-dimethyleneazabicyclo[3.1.1] heptanes, in high yields (see scheme; IPr=N,N′-bis (2,6-diisopropylphenyl) imidazol-2-ylidene). © 2009 Wiley-VCH Verlag GmbH & Co.
