Description	The [2+2+2] cyclotrimerization of 1-isoquinolinyl-1,7-octadiyne with benzonitrile catalyzed by CpCo(CO)2 opened a new pathway for a synthesis of unsymmetrical axially chiral bipyridine N,N’-dioxides. The N,N’-dioxide 3a was found to be highly catalytically active and enantioselective for the asymmetric allylation of aldehydes with allyltrichlorosilane. The allylation took place with even 1% of the catalyst with an enantioselectivity up to 87% ee.

N,N’-dioxid 3a je vysoce katalyticky aktivní a enantioselektivní v asymetrické allylaci aldehydů allyltrichlorosilanem. Allylace probíhá i s 1% katalyzátoru s enantioselektivitou až 87% ee. (cs)
