The C1–C11 subunit of tedanolide was constructed using a boron-mediated syn aldol reaction as the key step to control the C6 and C7 stereocenters. Other features of this work include the asymmetric Sharpless dihydroxylation to incorporate the C2, C3 hydroxyl groups, selective protection of the hydroxyl group at C2 as well as the usage of a tert-butyl ester to tolerate the attack of Grignard and enolate
使用硼介导的顺式醇醛缩合反应作为控制C 6和C 7立体中心的关键步骤,构建了泰达内酯的C 1 -C 11亚基。这项工作的其他功能包括不对称二羟基化夏普勒斯掺入的C 2,C 3羟基基团,在C羟基的选择性保护2以及的使用一叔丁基酯容忍格利雅和烯醇化物试剂的攻击。
