Overman rearrangement have been developed for the highly selective synthesis of anti-vicinal amino alcohol natural products. A MOM ether-directed palladium(II)-catalyzed rearrangement of an allylic trichloroacetimidate was used as the key step for the preparation of the protein kinase C inhibitor d-erythro-sphinganine and the antitumor agent (+)-spisulosine, whereas the Overman rearrangement of chiral
已经开发了 Overman 重排的两种变体,用于抗连位氨基醇天然产物的高选择性合成。MOM 醚导向钯 (II) 催化的烯丙基三氯乙酰亚胺重排被用作制备蛋白激酶 C 抑制剂d-赤型-二氢鞘氨醇和抗肿瘤剂 (+)-spisulosine的关键步骤,而 Overman 重排手性烯丙基trichloroacetimidates通过不对称还原的α产生,β不饱和甲基酮允许快速访问既d -核糖-phytosphingosine和升-阿拉伯-phytosphingosine。
