The total synthesis of borrelidin has been achieved. The best feature of our synthetic route is SmI(2)-mediated intramolecular Reformatsky-type reaction for macrocyclization after esterification between two segments. The two key segments were synthesized through chelation-controlled carbotitanation, chelation-controlled hydrogenation, stereoselective Reformatsky reaction, and MgBr(2).Et(2)O-mediated
已经实现了硼瑞林的全合成。我们的合成路线的最大特点是SmI(2)介导的分子内Reformatsky型反应的两个部分之间酯化后的大环化反应。这两个关键部分是通过螯合控制的氨基甲酸酯化,螯合控制的氢化,立体选择性Reformatsky反应和MgBr(2).Et(2)O介导的螯合控制的烯丙基化合成的。[反应:看文字]
