- Benzo-aza-alkyl aryl piperazine derivative and applications in preparation of drugs
-
The invention discloses a benzo-aza-alkyl aryl piperazine derivative and applications in preparation of drugs. The derivative shows the effect on central nervous systems, especially on the double highaffinity activity of a 5-HT acceptor and a Sigma-1 acceptor. Various physiological and pharmacological effects are brought into play in the body; and the compound can be used as a pharmaceuticalactive substance, especially used for anti-depression, anti-anxiety, anti-bipolar affective disorder and anti-neuropathic pain, and can also be used as an intermediate to prepare other pharmaceuticalactive compounds. The compound is fast in effect and small in toxic and side effect, and can meet demands of clinical applications; and the compound is a compound or a free base or salt thereof havingthe following structural formula (IV). The structure of the compound or the free base or salt thereof is shown as the structural formula (IV).

- Towards the synthesis of aminodibenzo[b,e][1,4]dioxin derivatives via cationic ruthenium complexes
-
Double nucleophilic aromatic substitution reactions between N-substituted (η6-1,2-dichlorobenzene)RuCp+ salts and substituted 1,2-benzenediols have been carried out under mild conditions to prepare N-substituted (η6-dibenzo[b,e][1,4]dioxin)ruthenium(II) complexes. The dibenzodioxin ligands were subsequently liberated by photolysis, with radiation from a sunlamp or from a medium pressure Hg lamp (300 nm).
