    Incorporation of a Molecular Hinge into Molecular Tweezers by Using Tandem Cycloadditions onto 5,6-Dimethylenenorbornene
    摘要:
    Site-selective 1.3-dipolar coupling at the norbornene pi -bond of 5,6-dimethylenenorbornene I yields cycloadducts with an end-fused 1.3-diene system which have been reacted with N=N (or C=C) dienophiles to produce ribbon molecules. in which the internal diazacyclohexene (or cyclohexene) subunits are capable of acting as conformational hinges. Direct coupling of 5,6-dimethylene- norbornene with 1.3,4-oxadiazoles or dual coupling with bis(cyclobutene epoxides) afforded bis(1,3-dienes) that diastereoselectively react with dienophiles to produce new. conformationally mobile. molecular tweezers.

  • The unusual reaction of tetrachlorothiophene dioxide with an adduct of 5,6-bismethylenenorbornene and hexachloronorbornadiene

    Hexachloronorbornadiene forms a 1 : 1 adduct 3 with 5,6-bismethylenenorbornene, which, on reaction with 1,2,3,4-tetrachlorothiophene dioxide, yields by loss of SO2, cycloreversion and further cycloaddition two compounds shown by mass, 13C NMR and 1H NMR spectroscopy and a single-crystal X-ray structure determination to be the isomeric products of a rare type of specific diene-capture by perchlorothiophene dioxide; a rational explanation for this and other examples is proposed, and a further example of norbornene sp2C pyramidalisation is disclosed.

The results are rationalized by invoking anchimerically assisted ionization of the exo-brosylate 11 to symmetrical ion-pairs (cyclopropylcarbinyl cation intermediates) which undergo internal (and probably also external) return. Acetolysis of the endo-brosylate 12 is not anchimerically assisted and leads initially to non-symmetrical ion pairs. These evolve to symmetrical

Highly stereoselective, pressure-induced Diels-Alder reactions of the bis-dienophiles 8a and/or 9a with the bis-diene 7 lead to the sterically rigid macrocycles 1a, 2a, and 3a/3b, which have well defined cavities of different sizes.

  • Low and high temperature bromination of exocyclic dienes: high temperature bromination. Part 16
    作者:Nurhan Horasan (Kishali)、Yunus Kara、Akin Azizoğlu、Metin Balci

    The electrophilic addition of bromine to an exocyclic diene, 5,6-dimethylenebicyclo[2.2.1]hept-2-ene, in CCl4 at 0°C led to the formation of non-rearranged (73%) and rearranged products (27%). However, high temperature bromination of the exocyclic diene at 77°C suppressed the formation of the rearranged products. Similarly, bromination of 9,10-dimethylenetricyclo[6.2.1.02,7]undeca-2,4,6-triene at −10°C
    在0°C下于CCl 4中将溴亲电加到环外二烯5,6-二亚甲基双环[2.2.1]庚-2-烯中,导致未重排(73%)和重排产物的形成(27 %)。但是,在77℃高温环溴二烯的溴化反应抑制了重排产物的形成。类似地,在-10℃下溴化9,10-二亚甲基三环[6.2.1.0 2,7 ] undeca -2,4,6-三烯仅得到外--1,-加成产物。在+ 5℃下溴化导致形成由比例为(1:4)的外型-1,2-和1,4-加成产物组成的混合物。77°C的高温溴化导致内膜的形成-1,2加成产品。此外,已经表明1,4-加成产物平稳地转化为1,2-加成产物。对产品的形成机理进行了讨论并得到了计算的支持。

    4-triazole-3,5-dione (PTAD) was subjected to a triplet-sensitized di-π-methane rearrangement. Hydrolysis of the resulting urazol 18 gave the hydrocarbon 7. Hydrolysis of 18 at lower base concentrations led to isomeric stable semicarbazides 24 and 25, which were submitted NiO2 or MnO2 oxidation, to give the target compound 7, and oxidation products 26 and 27.
