Studies show that a variety of conjugated dienes and triene can be enantioselectively diaminated using di-tert-butyldiaziridinone as nitrogen source and chiral N-heterocyclic carbene-Pd(0) complex as catalyst in good enantioselectivity (62-91% ee) with high regio- and diastereoselectivity.
研究表明,使用二叔丁基二氮杂环丙烷作为氮源,手性N-杂环卡宾-Pd(0)配合物作为催化剂,可以对多种共轭二烯和三烯进行对映选择性二胺化反应,具有良好的对映选择性(对映体过量62-91%)以及高区域和非对映选择性。
