naturally occurring molecules and remain some of the most rigorously studied antitumor compounds to date. Herein we describe a total synthesis of the (±)-CC-1065 CPI subunit in an overall yield of 9.3% from commercially available 5-fluoro-2-nitrophenol. The key steps of this synthesis are a Diels−Alder reaction of an o-benzoxy-monoimine quinoid and an intramolecular aryl triflate amidation, which formed
CC-1065和相关的杜卡霉素是天然存在的分子结构独特的家族的成员,并且仍然是迄今为止研究最严格的一些抗肿瘤化合物。在本文中,我们描述了从商业上可得到的5-氟-2-硝基苯酚以(9.3)%的总收率合成(±)-CC-1065 CPI亚基的全合成。该合成的关键步骤是邻苯甲酰基单亚胺喹啉和分子内芳基三氟甲磺酸酰胺化的Diels-Alder反应,这形成了吡咯并[3,2- f ]四氢喹啉中间体,通往CPI。
