the five membered ring have been prepared and tested as catalysts in the cycloisomerization of enynes. These new catalysts are very efficient, with the sulfoxide moiety playing a key role in their activity and the N1-substituent in control of the regioselectivity of these processes.
已经制备了具有连接在五元环的C 4位上的手性亚砜基的
金中离子卡宾,并在烯炔的环异构化中作为催化剂进行了测试。这些新催化剂非常有效,亚砜部分在其活性中起着关键作用,而N 1-取代基在控制这些过程的区域选择性中起着关键作用。
