Convergent total syntheses of murisolin (1), natural 16,19-cis-murisolin 2, and unnatural 16,19-cis-murisolin 3 were accomplished by asymmetric alkynylation of alpha-tetrahydrofuranic aldehyde with a diyne and Sonogashira coupling with a gamma-lactone segment as the key steps. Stereoisomers of alpha-tetrahydrofuranic aldehyde were synthesized with high optical purity and the asymmetric alkynylation
穆里索林(1),天然16,19-顺式-穆里斯林2和非天然16,19-顺式-穆里斯林3的聚合总合成是通过α-四氢呋喃醛与二炔和Sonogashira与γ-内酯的不对称烷基化反应完成的细分作为关键步骤。合成具有高光学纯度的α-四氢呋喃醛的立体异构体,并以高收率和高非对映选择性进行这些与1,6-庚二炔的不对称炔基化反应。还研究了合成化合物1-3的细胞生长抑制特征和COMPARE分析。
