Full textThe known transformation of bromotricycloheptane 4 into the homoallylalcohol 76 by hydroboration/oxidation was performed different to the earlier procedure by using in the first step a THF solution of borane generated in situ from sodiumborohydride and elemental iodine. Furthermore chlorotricycloheptane 26 and methyltricycloheptane 62 could be transformed into the homoallylalcohol 108 and 109, respectively, by using the same reaction conditions. Beside 4, 26, 62 and phenyltricycloheptane 15, which hydroboration/oxidation to homoallylalcohol 45a succeeded earlier, a variety of bicyclo[1.1.0]butane derivatives was treated with borane and then the mixture was oxidized. But no reaction resulted in a product analogous to the homoallylalcohols 45a, 76, 108 and 109. About the reason for the failure of these reactions at this time only can be speculated. However, in the case of 3,4-benzotricyclo[4.1.0.02,7]heptane (83) evidence was given for formation of oligomers from the substrate. The ability to stabilize a positive charge of the substituents at the tricycloheptane system is to be considered as a reason for the addition of borane to 4, 15, 26 and 62. Based on the transformation of 4 with trideuteroborane certain reaction mechanisms, for example that via the rearrangement product 119 of 4 and hydroboration of 119, were excluded and that with the zwitterion 120 was supported. 120 should rearrange through a 1,2-shift of deuteride into cyclohexenylmethylborane 121 which is seen as a precursor in the oxidation reaction to the isolated product 87. The reactions of 4 and 15 with 9-borabicyclo[3.3.1]nonane (9-BBN) followed by oxidation of the mixture generated depending on the addition rate of 9-BBN to the substrate the dialcohols 122 and 123, respectively, in both cases as a diastereomeric mixture and/or the homoallylalcohol 76 and 45a, respectively. Zwitterions 124, trialkylboranes 125, zwitterions 127 and trialkylboranes 128 and 129 are considered as precursors for the compounds 122 and 123. The zwitterions 124 should be formed by addition of 9-BBN to the substrates 4 and 15 and should be transformed by hydride shift into 125 which should give rise to zwitterions 126 and then 127 after addition of 4/15. 1,2-Shift of a carbon atom of the eight-membered ring should lead to 128 and 129 which should be transformed into 122/123 by oxidation. Dimesylate exo,exo-142 was obtained in a more step reaction via the known dibromodialcohol 148 starting from benzvalene (82). The alcohol groups of 148 were protected with trimethylsilyl chloride by formation of the bis(silyl ether) 151. Bicyclo-butane exo,exo-152 was obtained from 151 by reaction with tert-butyllithium. After removing the protecting groups with potassium carbonate in methanol the dialcohol exo,exo-150 was formed. This alcohol reacted with methanesulfonyl chloride to the target molecule exo,exo-142. The reaction of a 2:1 mixture of exo,exo-150 and 157 with sodium hydride and iodoethane generated the bis(silyl ethers) 160 and 161 in 38% and 19% yield, respectively. For the solvolyses reactions a 36:1:16 mixture of exo,exo-142, endo,endo-142 and 159 was used. After reacting the mixture in 60% acetone/water in the presence of triethylamine at 40 °C during five days the NMR spectra showed a decrease of exo,exo-142 by 75% (determined by using 159 as internal standard) while no product could be identified. The ethanolysis at 40 °C during three days in the presence of triethylamine produced a 3.5:2.8:1.0 mixture of exo,exo-142, 159 and 162. The compound 162 was formed with 70% yield (based on exo,exo-142 consumed). The NMR spectra showed that the proportion of exo,exo-142 had decreased by 30% (determined by using 159 as internal standard). After seven days using the same reaction conditions the proportion of exo,exo-142 decreased by 50% (determined by using 159 as internal standard) and a 1:1:1 mixture of exo,exo-142, 159 and 162 was obtained. 162 was formed with 50% yield (based on exo,exo-142 consumed). Solvolysis in 2,2,2-trifluoroethanol at 40 °C during three days in the presence of triethylamine produced a 3.2:2.0:1.0 mixture of exo,exo-142, 159 und 163. In the NMR spectra a decrease of exo,exo-142 by 20% was observed (determined by using 159 as internal standard). The solvolyses reactions of the dimesylate exo,exo-142 proceed, in contrast to those of its diastereomer endo,endo-142, solely with formation of unrearranged products and therefore they offer for the first time strong evidence for the intermediacy of a bicyclo[1.1.0]-but-2-exo-ylcarbinyl cation (166). It should be expected that the compounds 162 and 163 solvolyses on their part to give the bis(ethyl ether) 160 and its hexafluoro-derivative, respectively, but these compounds are not stable under the solvolyses conditions. This was proved by a control experiment
