Enantioselective synthesis of phomallenic acid C, an inhibitor of bacterial FAS II pathway, was successful. Allenyldiyne structure was constructed by a direct anti-SN2′ coupling of propargyl mesylate with diynylindium in the presence of palladium catalyst. Enantiomeric purity was determined by Ohrui–Akasaka method to be 83%ee.
细菌FAS II途径抑制剂磷丙二酸C的对映选择性合成成功。烯丙基二炔结构是通过在钯催化剂存在下,将炔丙基甲磺酸酯与二炔基吡啶直接抗-S N 2'偶联而构建的。通过Ohrui–Akasaka方法测定对映体纯度为83%ee。
