(+)-Fusarisetin A属于一组具有潜在抗癌活性的酰基四酸天然产物。Equisetin是一种与生物遗传相关的酰基四酸,它包含(+)-fusarisetin A的基本骨架。我们提出了Equisetin和(+)-fusarisetin A共有一种生物合成途径,该途径从天然存在的(S)-丝氨酸和不饱和脂肪开始酸。为支持该假设,我们证明了涉及分子内Diels-Alder反应的环化序列,随后是聚烯酰氨基酸的Dieckmann环化,产生了equsetin。Mn III / O 2促进的马鞭草蛋白酶的好氧氧化 或通过可见光化学产生的活性氧(ROS)产生的过氧化富铁链霉菌素,可以很容易地还原为(+)-富沙糖链菌素A。
The first total syntheses of two cernuane-type Lycopodiumalkaloids, (-)-cernuine and (+)-cermizine D, were accomplished starting from (+)-citronellal. The syntheses involved organocatalytic alpha-amination to afford oxazolidinone, which is used for diastereoselective allylation, and asymmetric transfer aminoallylation followed by stereoselective construction of an aminal moiety as key steps.
Starting from equisetin, the asymmetricsynthesis of (+)‐fusarisetin A has been accomplished in a one‐pot transformation including a biomimetic oxidation and an intramolecular Diels–Alder/Roskamp reaction. Peroxyfusarisetin is proposed as a plausible biosynthetic intermediate based on studies of the oxidation of equisetin.

Total synthesis of (-)-mintlactone and (+)-isomintlactone has been achieved diastereoselectively via a fused butenolide construction strategy based on an intramolecular [3+2] cycloaddition reaction of nitrile oxide.
