赤霉素A环重排反应催化剂研究

Catalysts studies on the rearrangement of ring A of gibberellins

摘要: 简介了赤霉素A环的重排反应,即1,2位及1,10位之间双键的移动及相应内酯环的重排.在利用重排反应构建赤霉素A环的1,2位双键时,首次发现商品化试剂苯基二氯化硼与二苯基溴化硼及二甲基溴化硼一样可用于催化此反应.

Abstract: The results of ring A rearrangement of gibberellin,involvinging double bond migrations between 1,2-and 1,10-positions and formation of lactone rings,were reported.It is first discovered that phenylboron dichloride plays a very similar roles of catalyst as diphenylboron bromide or dimethylboron bromide in the reaction.
