  1. My prof tells me there a more than one way to name these compounds: both the derviation from the bridged naphtalene/benzodixine ringsystem as well as from the tricyclic undecadiene ringsystem are possible. Well, that settels that!
  2. sue vs use <-- nice one anyway, tried again with a bit more reading and carefull thinking (only counting hydros that are actually new to basic structures of the naphthalene/bensodioxine rings) and came up with these (I dropped the Stereo, since that's already settled): 1a+b) 4a,8a-dichloro-5,8-dihydro-1,4-methanonaphthalene-1,4-dicarbonitrile 2a+b) 6,7-dichloro-4a,5,8,8a-tetrahydro-1,4-methanonaphthalene-1,4-dicarbonitrile 3a+b) 4a-methoxy-2,3,8a-trihydro-5,8-methanobenzo[1,4]dioxine-5,8-dicarbonitrile puh ~ that was a long day(s) work. I'm gonna talk to my prof about these names tomorrow, and see what he thinks of them.
  3. Not my intention to sue anyone. I was just pointing out why I was using other programs and that they apparently have trouble naming complex molecules correctly => thats why I asked for help here ...
  4. I don't have ChemDraw (does not work on my system), but ChemSketch (ACD) Possible Corrections: 1a) (1R,4S,4aS,8aR)-4a,8a-dichloro-1,4,4a,5,8,8a-hexahydro-1,4-methanonaphthalene-1,4-dicarbonitrile 1b) (1R,4S,4aR,8aS)-4a,8a-dichloro-1,4,4a,5,8,8a-hexahydro-1,4-methanonaphthalene-1,4-dicarbonitrile 2a) (1R,4S,4aR,8aS)-6,7-dichloro-1,4,5,6,7,8-hexahydro-1,4-methanonaphthalene-1,4-dicarbonitrile 2b) (1R,4S,4aS,8aR)-6,7-dichloro-1,4,5,6,7,8-hexahydro-1,4-methanonaphthalene-1,4-dicarbonitrile 3a) (4aS,5R,8S,8aR)-4a-methoxy-2,3,4a,5,8,8a-hexahydro-5,8-methanobenzo[1,4]dioxine-5,8-dicarbonitrile 3b) (4aR,5R,8S,8aS)-4a-methoxy-2,3,4a,5,8,8a-hexahydro-5,8-methanobenzo[1,4]dioxine-5,8-dicarbonitrile
  5. I tried putting the names together myself, now need someone to check them: 1a) (1R,4S,4aS,8aR)-4a,8a-dichloro-2,3,5,5,6,7,8,8-octahydro-1,4-methanonaphthalene-1,4-dicarbonitrile 1b) (1R,4S,4aR,8aS)-4a,8a-dichloro-2,3,5,5,6,7,8,8-octahydro-1,4-methanonaphthalene-1,4-dicarbonitrile 2a) (1R,4S,4aS,8aR)-6,7-dichloro-2,3,4a,5,5,8,8,8a-octahydro-1,4-methanonaphthalene-1,4-dicarbonitrile 2b) (1R,4S,4aR,8aS)-6,7-dichloro-2,3,4a,5,5,8,8,8a-octahydro-1,4-methanonaphthalene-1,4-dicarbonitrile 3a) (1R,4S,4aS,8aR)-4a-methoxy-5,8-dioxa-2,3,6,6,7,7,8a-heptahydro-1,4-methanonaphthalene-1,4-dicarbonitrile 3b) (1R,4S,4aR,8aS)-4a-methoxy-5,8-dioxa-2,3,6,6,7,7,8a-heptahydro-1,4-methanonaphthalene-1,4-dicarbonitrile Hope someone can help me with this, sumi
  6. Sadly no -.- I do but both ACD/ChemSketch and ChemAxon/MarvinSketch give me these apparently false names: (1a) (1R,2S,7R,8S)-4,5-dichlorotricyclo[6.2.1.02,7]undeca-4,9-diene-1,8-dicarbonitrile (1b) (1R,2R,7S,8S)-4,5-dichlorotricyclo[6.2.1.02,7]undeca-4,9-diene-1,8-dicarbonitrile (2a) (1R,2S,7R,8S)-2,7-dichlorotricyclo[6.2.1.02,7]undeca-4,9-diene-1,8-dicarbonitrile (2b) (1R,2R,7S,8S)-2,7-dichlorotricyclo[6.2.1.02,7]undeca-4,9-diene-1,8-dicarbonitrile (3a) (1R,2S,7R,8S)-2-methoxy-3,6-dioxatricyclo[6.2.1.02,7]undec-9-ene-1,8-dicarbonitrile (3a) (1R,2R,7S,8S)-2-methoxy-3,6-dioxatricyclo[6.2.1.02,7]undec-9-ene-1,8-dicarbonitrile
  7. Hi, I have a problem figuring out the name of these compounds (see attachment): .mol files are attached in a .zip file. Hope someone can help me with this, sumi mol files.zip
  8. Hi, I have a problem figuring out the Mechanismus for this rxn: 2-nitroresorcinol + 4-penten-1-ol --> 2-Nitro-1,3-bis(pent-4-enyloxy)benzene --> 2,6-Bis(pent-4-enyloxy)aniline Hope someone can help me with this, sumi
