and hydroxylation reactions to generate γ-hydroxylated lactams without the ring-opened products in extremely high yields, respectively. This process was further applied to the total synthesis of an isoindolobenzazepine alkaloid, chilenine, by featuring the elaboration of the functionalized phthalimide derivative.
发现在室温下用路易斯酸(如亚铜或卤化铜)在室温下用路易斯酸处理各种脂环族和芳香族γ-苯硫基取代的内酰胺会发生新型的串联脱硫和羟基化反应,从而生成没有开环产物的γ-羟基内酰胺分别具有极高的产量。通过以功能化的邻苯二甲酰亚胺衍生物为精制工艺,该方法被进一步应用于异吲哚并苯并ze庚碱生物碱,嘌呤的全合成。
