Three syntheses of the protein kinase C activator, (-)-indolactam V, are described and are compared for their potential utility in the preparation of ILV analogs. In one route the 4-amino functionality is introduced regiospecifically during the construction of the indole portion and enantiomeric control is achieved by the alkylation of the amine with a triflate derived from d-valine. One of the routes
描述了三种蛋白激酶C激活剂(-)-吲哚内酰胺V的合成方法,并比较了它们在制备ILV类似物中的潜在效用。在一种途径中,在吲哚部分的构建过程中区域特异性地引入4-氨基官能团,并且通过胺与衍生自d-缬氨酸的三氟甲磺酸酯的烷基化来实现对映体控制。一种途径提供了外消旋的ILV,通过首次报道的吲哚内酰胺拆分可从中获得(-)-ILV。
