Ring Ketene And Its Derivatives,

Cyclohexenone,cyclohexenols and their derivate have been attained from nature resources.Many of them have all kinds of biological activity such as anti-tumor antiulcerative anticonvulsant antibiosis antasthmatic.In our previous research,it is found that cyclohexenone and be preparated by the method of alkynes reacting with water in methanol by the catalysis of cationic gold(Ⅰ) complexes and acid.And the same result was found by the catalysis of Hg(Ⅱ).4 cyclohexenones was attained from diynes using metal catalyst by hydration cyclization reaction..17 cyclohexenones derives was attained.It is expected that some new drugs would been found from them.In the other hand,C-C coupled reaction with the catalysis of chrial quaternary ammonium salt had been an attractive area.We did some work in the derivate of amino acid.We expect some stereoslective reactions would be found.
