3]-sigmatropic rearrangement has been used to access biologically important β,β′-dihydroxy α-amino acids. The rearrangement reported is highly stereoselective and offers excellent levels of remote stereocontrol. This strategy has been used to synthesize the natural immunosuppressant mycestericin G and ent-mycestericin G, allowing for a revision of absolute configuration of this natural product.
爱尔兰–克莱森[3,3]-σ重排已用于获取生物学上重要的β,β'-二羟基α-氨基酸。报告的重排具有很高的立体声选择性,并提供出色的远程立体声控制水平。该策略已被用于合成天然免疫抑制剂mycestericin G和ent -mycestericin G,从而允许修改该天然产物的绝对构型。
