The Weinreb amides 2a,b were prepared from the α,α-dimethoxyacetic acids 1c,d. A number of representative nucleophilic additions (RMgX and RLi) on 2 afforded α-ketoacetals 3a–j in 70–99% yield. These compounds represent a versatile arrangement of functional groups of significant synthetic value, as demonstrated in the synthesis of (±)-salbutamol.
Weinreb酰胺2a,b由α,α-二甲氧基乙酸1c,d制备。在2上进行多种典型的亲核加成(RMgX和RLi),以70-99%的产率得到了α-酮缩醛3a-j。这些化合物代表着具有重要合成价值的多种官能团的灵活排列,如合成(±)-沙丁胺醇所示。
