A highly chemoselective and reactive μ‐oxo‐dinuclear iron(III) salen catalyst for transesterification was developed. The developed iron complex catalyzed acylation of aliphatic amino alcohols with nearly perfect O‐selectivity, even when using activated esters, for which chemoselectivity is more difficult to control. In addition, O‐selective transesterification of aromatic amino alcohols was achieved
开发了一种用于酯交换反应的高度化学选择性和反应性的μ-氧-双核铁(III)salen催化剂。发达的铁络合物催化脂肪族氨基醇的酰化反应,具有几乎完美的O选择性,即使使用活化酯,其化学选择性也更难控制。此外,首次实现了芳族氨基醇的O选择性酯交换。铁络合物的高活性使得能够使用空间上充斥的叔醇,包括前所未有的叔丁醇。
