A convergent synthesis of bafilomycin A1, a potent inhibitor of V‐type ATPases, is presented. The synthesis relies on the zinc triflate mediated diastereoselective addition of a complex enyne to a sensitive aldehyde as the key fragment coupling. A ruthenium‐catalyzed trans‐reduction of the resulting propargylic enyne efficiently installs the required C10–C13 trans,trans‐diene subunit, implementing
介绍了bafilomycin A 1的收敛合成,bafilomycin A 1是V型ATP酶的有效抑制剂。合成依赖于三氟甲磺酸锌介导的复杂烯炔向非对映体的非对映选择性加成,作为关键片段偶联的敏感醛。钌催化的炔丙基炔的反还原可有效地安装所需的C10–C13反式,反式二烯亚单元,从而实现了传统钯催化交叉偶联策略的替代策略。三元醇中仲羟基的高度选择性氧化为合成完成奠定了基础。
