The utility of hydroxylamines as nitrogen nucleophiles was investigated in the iridium-catalyzed regio- and enantioselective allylic substitution. Allylic substitution with hydroxylamines proceeded with good enantioselectivities by using the iridium-complex of bis(oxazolinyl)pyridine ligand. The good regio- and enantioselectivities were also achieved in the reaction with alkylamines, p-anisidine, and 4-methoxyphenol.
研究了羟胺作为氮亲核物在铱催化的区域和对映选择性烯丙基取代中的作用。通过使用双(噁唑啉基)吡啶配体的铱络合物,羟胺的烯丙基取代反应具有良好的对映选择性。在与烷基胺、对甲氧基苯胺和 4-甲氧基苯酚的反应中也实现了良好的区域和对映选择性。
