  First Synthesis of the Antifungal Oidiolactone C from trans-Communic Acid:  Cytotoxic and Antimicrobial Activity in Podolactone-Related Compounds

  摘要：

  The synthesis of the fungicide oidiolactone C starting from diterpenic trans-communic acid was carried out with an overall yield of 11.7%. The key step in the process consists of a new bislactonization reaction catalyzed by Pd(H), which gives rise to the podolactone-type tetracyclic skeleton from a norlabdadienedioic acid. We also carried out a study of the structure-biological activity of different natural podolactones and their synthetic precursors. Thus, the highest cytotoxic activity was found in dienic dilactones with ether-type substitutions on C-17, whereas the closure of the gamma-lactone ring is not critical for presenting a maximal antimicrobial activity.

  A new route to phenol abietane diterpenes from trans-communic acid is reported. The key step is the transformation of a β-ketoester into the corresponding O-acetylsalicilate, via a manganese(III)-based oxidative free-radical cyclization carried out in AC 2 O. Utilizing this, the first synthesis of (-)-sugikurojin A has been achieved. The immunosuppressor 19-hydroxyferruginol has also been synthesized

  Building with berries! Several labdane natural products have been synthesized for the first time by the combination of a copper‐catalyzed vinyl oxirane ring expansion reaction with an abundant, inexpensive, chiral natural source (juniper berries; see scheme). These expedient (1–5 step) syntheses have resulted in the structural confirmations of five natural products and one reassignment. Reagent‐controlled

  Strong 5α-reductase inhibitors are extracted and fractionated from Thuja orientalisis and other similar crude drugs or they may be purified as diterpenes in isolated form. The inhibitors are used either on their own or as active ingredients of therapeutics in the treatment of diseases caused by the overactivity of 5α-reductase or the hypersecretion of androgens, such as male pattern baldness, androgenetic alopecia, hirsutism, acne, prostatomegaly and cancer of the prostate.
