)
n
—B are provided, wherein A is THIQ or a substituted derivative thereof and B is an aryl, cycloalkylaryl, or cycloalkyl group, wherein A and B are linked to each other by an alkyl or substituted alkyl chain. The compounds are useful as selective ligands (agonists or antagonists) of central nervous system receptors, and in particular of the seratonin receptors. The compounds or their salts can be formulated into pharmaceutical in need thereof by any route of administration suitable for a desired treatment protocol and especially for the treatment of psychiatric disorders.

gem-aryl-disubstituted methylenecyclopropanes with TiX4/diethyl azodicarboxylate and TiX4/diisopropyl azodicarboxylate in 1,2-dichloroethane gave the dihalogenated ring-opened product, 2,4-dihalobut-1-ene, in moderate-to-excellent yields under mild conditions. On the basis of the proposed Orton-type mechanism, we found that this reaction can also be carried out with freehalogens such as bromine or iodine

The methylenecyclopropanes 1 react with LiCl, LiBr or NaI at 80 °C to give the corresponding gem-disubstituted homoallylic halides 2 in good to excellent yields in aceticacid. In some cases, the ring-openingreaction can be completed within 5 min to give the corresponding gem-disubstituted homoallylic halides in high yields.
