Ir(I)-catalyzed enantioselective decarboxylative allylic etherification of aryl allyl carbonates provides aryl allyl ethers. Key to the generality and high stereoselection of the reaction is the use of the intramolecular decarboxylative allylation process and [Ir(dbcot)Cl]2 as an Ir(I) source. Ir(I)-catalyzed diastereoselective decarboxylative allylic etherification, combined with asymmetric aldehyde
Ir(I)催化的芳基碳酸烯丙酯的对映选择性脱羧烯丙基醚化反应提供了芳基烯丙基醚。反应的一般性和高立体选择的关键是使用分子内脱羧烯丙基化过程和[Ir(dbcot)Cl] 2作为Ir(I)来源。Ir(I)催化的非对映选择性脱羧烯丙基醚化反应,与不对称醛的crotylation和交叉复分解相结合,可以提供具有高非对映选择性的单保护的2-甲基-1,3-二醇(从简单的醛开始)。
