The total syntheses of (R)-goniothalamin (1), a styryl lactone isolated from several Goniothalamus species, via catalytic asymmetric allylation of alpha-benzyloxyacetaldehyde (2), followed by ring-closing metathesis and Wittig olefination and via catalytic asymmetric allylation of trans-cinnamaldehyde (12), followed by ring-closing metathesis are reported. The antiproliferative activities of (R)-1 and its Z-isomer 10 as well as of the synthetic dihydropyranone intermediates 7 and 8 against eight different cancer cell lines are also described.
从几种哥纳香属植物中分离得到的苯乙烯基内酯(R)-戈尼他胺(1)的全合成方法被报道,该方法通过α-苄氧基乙醛(2)的催化不对称烯丙基化反应,随后进行闭环复分解反应和维蒂希烯烃化反应,以及通过反式肉桂醛(12)的催化不对称烯丙基化反应,随后进行闭环复分解反应。还描述了(R)-1及其Z-异构体10以及合成二氢吡喃酮中间体7和8对八种不同癌细胞系的抗增殖活性。
