, p. 6938 - 6940 (2009)
Τhe synthesis of 3,7-diiodo-tricyclo[3.3.1.03,7]nonane, the main precursor of noradamantene, by iodination of the corresponding diol via its dimesylate affords a threefold higher yield than the direct iodination of the diol. Neither the dimesylate nor the cyclic sulfate of the diol yields noradamantene upon reduction with sodium amalgam.

(1) The compound 1 is reacted under the action of sodium ethoxide in a substitution reaction under the action of sodium ethoxide to form compound 2 by stirring and refluxing 2 under the action of sodium ethoxide to form compound 2; (8 hours) compound 3 is reacted 3 at room temperature under the alkaline condition by adding L - arginine to obtain a salvildagliptin intermediate, compound 3) and liquid bromine under the action of sodium ethoxide and then adding L-arginine under the action of sodium ethoxide under the action of sodium ethoxide and then 8 hours adding L-arginine 4 under the 4 action of 4 sodium ethoxide 12 hours. Raw materials and reagents are cheap and easily available, the reaction operation is simple, the reaction conditions are mild, the yield is high, the quality is good, the resolution end product can reach 99% ee values, and the requirements of drug intermediates are met.

Mixed simplified structures containing the paclitaxel and eleutherobin pharmacophore moieties were analyzed using molecular docking techniques and synthesized based on adamantane and 8-oxabicyclo[3.2.1]octane scaffolds. The crucial role of substituents' stereochemistry in biological activity is discussed. At micromolar concentrations the selected analogues interfered with tubulin dynamics in vitro and in a living organism. Furthermore, new compounds were cytotoxic against human tumour cell lines. The simplified eleutherobin analogues may be considered as prototypes of a new class of antitumour agents.
