migration strategy was applied in an efficient synthesis of the naturally occurring 6H-naphtho[1,2-b]benzopyran-6-one defucogilvocarcin V (1a, Scheme 11). The required biarylcarbamate 33d was best prepared by a high yielding Suzuki coupling reaction of 31a with the differentiallyprotected trioxygenated naphthalene coupling partner 32d which was synthesized using a selective acylation of a juglone derivative
关键的定向远程金属化(DreM)-氨基甲酰基迁移策略被用于有效合成天然存在的6H-萘并[1,2 - b ]苯并吡喃-6-一品烟脱氧叶绿素V(1a,方案11)。所需的联芳基氨基甲酸酯33d可以通过高产率的31a铃木偶联反应与受保护的三聚氧化萘偶联伴侣32d进行高产率的合成来制备,该偶联伴侣是通过使用juglone衍生物进行选择性酰化而合成的。在合成的后期阶段,三氟甲磺酸酯39担当了公共中间来安装所需的C-8乙烯基1A(Stille偶联)以及用于制备脱氢福尔霉素类药物M(1b)和E(1c)所需的取代基。对各种保护基团的策略进行了研究,并提供了有关DreM-氨基甲酰基迁移过程中首选哪个基团的见解。从这种全合成过程中学到的战略经验被应用在结构相似的天然产物芦丁素I(2)的成功全合成过程中。
