[reaction: see text] The aldol reaction of acetamide enolates with protected chiral alpha-amino-beta-hydroxy aldehyde 1 (Garner's aldehyde) has been performed in a stereocontrolled way under double stereodifferentiation conditions using pseudoephedrine as the additional chiral information source attached to the enolate reagent. In addition, the obtained adduct has been transformed into other valuable chiral building blocks such as gamma-amino-beta,delta-dihydroxy acids, esters, and ketones.
[反应：见正文] 以伪麻黄碱作为连接在烯醇盐试剂上的额外手性信息源，在双立体分化条件下，乙酰胺烯醇盐与受保护的手性α-氨基-β-羟基醛1（加纳醛）进行了立体控制的羟醛反应。此外，所得到的加合物已被转化为其他有价值的手性结构单元，如γ-氨基-β,δ-二羟基酸、酯和酮。
