Asymmetric intermolecular conjugate addition of α-amino acid derivatives with 4 via memory of chirality has been developed. The reactions proceeded in up to 98% ee with retention of configuration at the newly formed tetrasubstituted carbon center when R = Me. The product (R = Me) was transformed into manzacidin A.
已经开发了通过手性记忆的α-氨基酸衍生物与4的不对称分子间共轭加成。当R = Me时,反应以高达98%ee的温度进行,并保留了新形成的四取代碳中心的构型。产物(R = Me)被转化为甘露糖苷A。
