  摘要：

  (R)-1-(4-(2,5-Dihydro-3-methyl-5-oxothien-2-ylidene)-4-(3-methyl-2-thienyl)butyl)-3- piperidinecarboxylic acid (5-hydroxytiagabine) 13, has been prepared in 8 steps from 2-bromo-3-methylthiophene 3. Key steps are Grignard reactions, displacement of heteroaromatic chlorine with methoxy, and simultaneously demethylation and opening of a hydroxymethylcyclopropane with bromotrimethylsilane. An alternative approach involving acylation of 2-lithio-3-methylthiophene 17a was found less satisfying. A metalloporphyrin assisted hydroxylation of tiagabine 1 also yielded the target metabolite. The structure of 5-hydroxytiagabine was confirmed by NMR-data including COSY, ROESY, HMQC and HMBC experiments.

  The synthesis of some 4-hydroxy-(or amino)-ethyl-amino butyrophenones or butyrothienones is described. The interconversion of these compounds to the corresponding 5-aryl-4-oxa-1-azabicyclo[3,3,0]octanes is presented. The title compounds demonstrated good antiinflammatory activity in the adjuvant induced disease model. They also possessed antinociceptive, immuno-modulating and antioxidant activity, properties which are probably involved in the mechanism of their action.
