A highly enantioselective kinetic resolution of racemic 1,3-amino alcohols via O-Acylation was achieved using a chiral organotin as the catalyst. Alkyl- and aryl-substituted 1,3-amino alcohols were resolved with excellent efficiencies to afford the recovered 1,3-amino alcohols and acylative products with high enantioselectivities, with s factors up to >600. Notably, the chiral organotin catalyst was
使用手性有机锡作为催化剂,通过O-酰化实现了外消旋 1,3-氨基醇的高度对映选择性动力学拆分。烷基和芳基取代的 1,3-氨基醇以优异的效率分离,得到回收的 1,3-氨基醇和具有高对映选择性的酰化产物,s因子高达 >600。值得注意的是,手性有机锡催化剂对反-1,3-氨基醇的选择性高于顺式异构体。使用 2 mol% 催化剂负载的克级反应证明了该协议的实用性。
