An iridium-catalyzed asymmetric synthesis of branched allylic phosphine compounds under mild conditions is reported. Products bearing various functional groups can be synthesized with excellent stereoselectivity (up to 99.9 % ee) and regioselectivity. The employment of phosphine sulfides with relatively low deactivation capacity against metal catalysts is crucial for the success of this reaction.
报道了在温和条件下铱催化的支链烯丙基膦化合物的不对称合成。可以合成具有各种官能团的产品,具有出色的立体选择性(高达 99.9% ee)和区域选择性。使用对金属催化剂具有相对较低失活能力的硫化膦对于该反应的成功至关重要。
