Abstract

The bis-homo Diels–Alder reactions of maleimide and N-methylmaleimide with quadricyclane are shown to produce mixtures containing both the exo,anti- and exo,syn-tricyclo-[4.2.1.02,5]nona-7-ene-3,4-dicarboximides, whereas the isomeric endo,anti-adducts are available from the reaction of cyclopentadiene with the appropriate cyclobutene-3,4-dicarboximides. The related reaction of quadricyclane with maleic anhydride had been erroneously reported to form single adducts; our work shows that two stereoisomers are actually formed and these have been chemically related to the maleimide and N-methylmaleimide adducts. The proton chemical shifts of the adduct formed by reaction of cyclobutene-3,4-dicarboxylic anhydride with cyclopentadiene have also been miss-assigned. Preparation of [3] and [5] polynorbornane scaffolds with terminal succinimides have been effected by coupling the stereoisomeric adducts at the norbornene π-bond by using 2,5-bis(trifluoromethyl)-1,3,4-oxadiazole and bisepoxide. The spacer shapes and dimensions have been determined by molecular modelling.

  • 8 All new compounds gave satisfactory 1H and 13C NMR and high-resolution mass spectra. Quadricyclane Cycloaddition; Typical Procedure for the Preparation of 18 and 19: Quadricyclane (280 mg, 30 mmol) and N-methylmaleimide (333 mg, 30 mmol) in toluene (20 mL) were heated to reflux for 18 h. Evaporation of the solvent gave an off-white solid (540 mg, 88%), that was shown (1H NMR) to be a mixture of isomers 18 (88%) and 17 (19%). A sample of this mixture (112 mg) was separated by HPLC (reverse phase) to afford the pure components. Compound 18: Yield: 52 mg; mp 100.5–101 °C. 1H NMR (300 MHz, CDCl3): δ = 1.50 (d, J = 9.7 Hz, 1 H), 1.60 (d, J = 9.7 Hz, 1 H), 2.15 (br s, 2 H), 2.71–2.72 (m, 2 H), 2.98 (br s, 2 H), 3.02 (s, 3 H), 6.04–6.05 (m, 2 H). 13C NMR (75 MHz, CDCl3): δ = 25.0, 40.6, 40.9, 41.3, 44.2, 135.7, 178.9. HRMS (EI): m/z calcd for C12H13NO2: 203.0946; found: 203.0942. Compound 19: Eluted first; yield: 11 mg; mp 148–149 °C. 1H NMR (300 MHz, CDCl3): δ = 0.99 (d, J = 10.9 Hz, 1 H), 1.23 (d, J = 10.9 Hz, 1 H), 2.45–2.46 (m, 2 H), 2.93 (s, 3 H), 3.01 (d, J = 1.7 Hz, 2 H), 3.31–3.32 (m, 2 H), 6.04–6.05 (m, 2 H). 13C NMR (75 MHz, CDCl3): δ = 24.8, 36.7, 37.4, 41.7, 42.1, 137.2, 178.9. HRMS (EI): m/z calcd for C12H13NO2: 203.0946; found: 203.0942.
