[structure: see text] Herein we report the formal total synthesis of (+)-discodermolide in 21 steps (longest linear sequence) from commercially available Roche ester. This synthesis features the assembly of C(9-18) and C(19-24) fragments via a metal-chelated aldol coupling reaction.
[结构:见正文] 在此,我们报道了以市售罗氏酯为原料,经21步反应(最长线性序列)实现(+)-片螺素的形式全合成。该合成的特点是通过金属螯合羟醛缩合反应组装C(9-18)和C(19-24)片段。
