R. Gilardi et al., AZA-ANALOGS OF CAGE COMPOUNDS - POTENTIAL PRECURSORS TO AZACUBANES AND 1-AZAHOMOCUBANES, Journal of heterocyclic chemistry, 30(5), 1993, pp. 1385-1388
Exploration of the reactions of the 9-azahomocubane system led to deri
vatives of two small-ring systems containing aza-bridging atoms, 5-aza
tetracyclo[4.2.0.0(3,8).0(4,7)]octane and 9-azatetracyclo[4.3.0.0(2,5)
.0(4,7)]nonane. The structures were characterized by X-ray diffraction
analyses. There are no prior X-ray structural reports on these system
s.
