Synthetic studies towards the C3–C13 (2) and C14–C24 (3) segments of the potent antiviral and antitumor compound macrolactin A (1) are presented. Segment 2 was constructed via a convergent and facile approach, exploiting Wittig olefination to generate the sensitive E,Z-diene moiety. Segment 3 was obtained from the chiral pool derived sulfone 4 via an α-alkylation–desulfonation reaction sequence.
提出了对有效的抗病毒和抗肿瘤化合物大内泌素A(1)的C 3 –C 13(2)和C 14 –C 24(3)部分的合成研究。片段2是通过收敛和简便的方法构建的,利用维蒂希(Wittig)烯化反应生成敏感的E,Z-二烯部分。片段3是通过手性池衍生的砜4通过α-烷基化-磺化反应序列获得的。
