Hml. Davies et al., RHODIUM(II)-CATALYZED DECOMPOSITION OF VINYLDIAZOMETHANES IN THE PRESENCE OF 1,2-DIHYDROPYRIDINES - SYNTHESIS OF THE 6-AZABICYCLO[3.2.2]NONANE NUCLEUS, Tetrahedron letters, 39(18), 1998, pp. 2707-2710
A series of functionalized 6-azabicyclo[3.2.2]nonadienes was synthesiz
ed via rhodium(II)-catalyzed decomposition of vinyldiazomethanes in th
e presence of substituted dihydropyridines. The regioselectivity of th
e reaction was shown to be highly dependent on the steric bulk of the
catalyst as well as the structure of the viny(diazomethane. Each regio
isomer was elaborated into higher homologs of ferruginine (1, 2). (C)
