Aurachins, a family of isoprenoid quinoline alkaloids isolated from the myxobacterium Stigmatella aurantiaca, possess multiple interesting bioactivities and were subject of intensive studies of biosynthesis. In this Letter, we describe the efficient few step total synthesis of the parent compound aurachin D and two isoprenoid analogues via Conrad–Limpach cyclization. The main antimicrobial and cytotoxic
Aurachins是从粘杆菌Stigmatella aurantiaca分离的类异戊二烯喹啉生物碱家族,具有多种有趣的生物活性,并且已受到生物合成的深入研究。在这封信中,我们描述了通过Conrad-Limpach环化有效地进行几步全合成的母体化合物aurachin D和两个类异戊二烯类似物。探索了这些衍生物的主要抗微生物和细胞毒性特征。
