A general procedure for the asymmetric synthesis of highly substituted 1,2-amino alcohols in high yield and diastereoselectivity is described that uses organometallic additions of a wide range of nucleophiles to tert-butylsulfinimines as the key step. The addition of organolithium reagents to these imines follows a modified Davis model. The diastereoselectivity for this reaction depends significantly
描述了以高收率和非对映选择性非对称合成高度取代的1,2-氨基醇的一般程序,该程序使用了多种有机金属加成至叔丁基亚氨基亚胺作为关键步骤。向这些亚胺中添加有机锂试剂遵循改良的Davis模型。该反应的非对映选择性极大地取决于亲核试剂和亲电试剂。这些高度取代的1,2-氨基醇可用于高收率合成立体化学多样且结构新颖的多取代2,2'-亚甲基(双恶唑啉)配体。
