  摘要：

  1,4-Functionalisation of cycloocta-1,3-diene using a nitroso-cycloaddition strategy is followed by intramolecular cyclisation to yield 9-azabicyclo[4.2.1]nonanes (homotropanes) and -non-7-enes (homotrop-7-enes); the approach can be adapted to allow access to 1-methylhomotropanes.

  Trop-6-ene (8-methyl-8-azabicyclo[3.2.1]oct-6-ene) and substituted N-benzylnortrop-6-enes are synthesised. N-Debenzylation of tropanes fails using a wide variety of non-hydrogenolytic conditions despite effective application in model piperidine derivatives; debenzylation of homotropanes is more successful, giving norhomotropane and norhomotrop-7-ene. Bridged N-benzyl compounds react more slowly than N-methyl analogues with chloroformates; the resulting quaternary intermediates are more prone than the N-methyl analogues to suffer competitive reversion to the starting amine, especially in the tropanes, consistent with slower S(N)2 attack at the benzylic carbon during decomposition; the use of an N-p-methoxybenzyl group does allow partial debenzylation to nortrop-6-ene, suggesting greater SNI character in the decomposition step in this case. 'Equatorial' attack is preferred in methylation of N-benzyl-nortrop-6-ene and -homotrop-7-ene with CH3I; subsequent reductive debenzylation of the quaternary salt achieves overall replacement of N-benzyl by N-methyl in both cases. VT NMR studies show the presence of a single 'equatorial' invertomer (Cl syn- to the 2C-bridge) in N-chloro-norhomotropanes and -7-enes and, by analogy, in the N-alkyl compounds.
