The C1–C14 fragment of the paclitaxel-like antimicrotubule agent laulimalide has been synthesized in 15 steps from l-(−)-citronellal. The C9 chiral center was established using an asymmetric allylation, the dihydropyran ring was prepared through ring-closing metathesis, and the exo-methylene was incorporated using Eschenmoser's salt.
紫杉醇样抗微管药laulimalide的C 1 – C 14片段是从1-(-)-香茅醛经15步合成的。使用不对称烯丙基化建立C 9手性中心,通过闭环易位制备二氢吡喃环,并使用埃森莫瑟盐掺入外亚甲基。
