The asymmetric ring-opening of azabicyclic alkenes with a variety of phenols is investigated using an iridium catalyst generated in situ from 2.5 mol % of [Ir(COD)Cl]2 and 5.0 mol % of (S)-BINAP, which afforded the corresponding 1,2-trans-phenoxyamino products in excellent yield (up to 92%) with moderate to good enantioselectivities (up to 98% ee). The trans-configuration of the product 4b was confirmed
使用由2.5 mol%的[Ir(COD)Cl] 2和5.0 mol%的(S)-BINAP原位生成的铱催化剂研究了氮杂双环烯烃与各种酚的不对称开环1,2-反式苯氧基氨基产物,收率极好(高达92%),对映选择性中等(良好)(高达ee高达98%)。通过X射线晶体学证实了产物4b的反式构型。
