S. Ottenshildebrandt et al., AMIDE-BASED FURANO-CATENANES - REGIOSELECTIVE TEMPLATE SYNTHESIS AND CRYSTAL-STRUCTURE, Journal of the Chemical Society, Chemical Communications, (7), 1995, pp. 777-778
The synthesis of the new octalactam catenane isomers 6 and 7 and the f
irst X-ray structural analysis of this skeleton are reported, revealin
g a self-assembled, interlocked system held together by networks of in
ter- and intra-molecular hydrogen bonds including the amide groups and
the furane oxygen atoms.
