A new strategy for highly concise, convergent, and enantioselective access to polydeoxypropionates has been developed. ZACA‐Pd‐catalyzed vinylation was used to prepare smaller deoxypropionate fragments, and then two key sequential Cu‐catalyzed stereocontrolled sp3–sp3 cross‐coupling reactions allowed convergent assembly of smaller building blocks to build‐up long polydeoxypropionate chains with excellent
已经开发了一种新的策略,可以高度简洁,收敛和对映选择性地获得聚脱氧丙酸酯。ZACA-Pd催化的乙烯基化用于制备较小的脱氧丙酸酯片段,然后两个关键的连续Cu催化的立体控制的sp 3 –sp 3交叉偶联反应使较小的结构单元收敛组装,从而形成了具有出色立体选择性的长聚脱氧丙酸酯链。我们采用了这种策略,仅用8个最长的线性步骤就可以完全合成结核分枝杆菌细胞壁脂质的关键成分苯硫醚酸。
