Mycotoxins of the tetrahydroxanthone class of natural products possess a large number of interesting biological properties. In this full paper, we present our synthetic strategy to some members of this class of compounds, namely the blennolides A and C. We disclose the scope and limitations of the functionalization of various xanthones derived from a domino oxa-Michael-aldol condensation and pursue
四氢氧杂蒽酮类天然产物的霉菌毒素具有许多有趣的生物学特性。在这篇完整的论文中,我们向此类化合物的一些成员介绍了我们的合成策略,即 blennolides A 和 C。我们公开了衍生自多米诺氧杂-迈克尔-羟醛缩合的各种氧杂蒽酮官能化的范围和局限性,并追求这些氧杂蒽酮的二聚化。此外,还获得了 blennolide C 的第一个晶体结构。
