produces a class of biogenetically related indole natural products that include hapalindoles and ambiguines. In this full account, a practical route to the tetracyclic hapalindole family is presented by way of an eight-step, enantiospecific, protecting-group-free total synthesis of (-)-hapalindole U that features an oxidative indole-enolate coupling. With gram-scale access to hapalindole U, the first total
蓝细菌的Stigonemataceae家族生产一类与生物遗传相关的吲哚天然产物,其中包括ha吲哚和双歧杆菌。在此全文中,通过八步,无对映体特异性,无保护基团的(-)-四氢吲哚U的全合成,提出了通往四环cyclic吲哚家族的实用途径,其特征在于氧化吲哚-烯醇酸酯偶联。以克级获得哈达吲哚U,通过异腈辅助的吲哚的异戊烯基化再进行光致碎裂级联反应,完成了含糊生物碱的第一个全合成(+)-含糊精H。
