opioid medicines. Here, a seven-step total synthesis of this natural product is reported from simple, commercially available starting materials. The pivotal aryl allyl ether substrate, which is obtained through successive Suzuki-Miyaura cross-coupling and Mitsunobu substitution reactions, was engaged in a double-Heck cyclization sequence. The tetracyclic product of these processes was subjected to
吗啡喃生物碱 (-)-蒂巴因是一种工业上重要的化学中间体,用于各种阿片类药物的半合成。在这里,这种天然产物的七步全合成是从简单的、可商购的起始材料报告的。通过连续的 Suzuki-Miyaura 交叉偶联和 Mitsunobu 取代反应获得的关键芳基烯丙基醚底物进行了双赫克环化序列。这些过程的四环产物经受光化学加氢胺化反应,产生包含完整五环吗啡喃骨架的N -Boc 哌啶衍生物。在另外三个简单的步骤中,最后一种化合物被转化为 (-)-蒂巴因。
