  立体构象的重新分配和Pericosine D o的绝对构型的合成方法测定

  摘要：

  化学合成和NMR方法的组合被用来重新分配percosine D o（8）的结构，percosine D o（8）是一种由真菌Periconia byssoides OUPS-N133产生的具有细胞毒性的海洋天然产物，最初源自海兔Aplysia kurodai。化学合成被用来从已知的氯醇制备pericoisne D o（8），而后者又衍生自（-）-奎宁酸。天然pericosine d的绝对构型Ô（8测定）为甲基（3- [R，4小号，5小号，6小号）-6-氯-3,4,5-三羟基-1-环己烯-1-羧酸酯。HPLC分析使用手性相柱表明pericosine d Ô（8）存在于自然界中的对映体纯的形式。

  An Electrophilic Natural Product Provides a Safe and Robust Odor Neutralization Approach To Counteract Malodorous Organosulfur Metabolites Encountered in Skunk Spray

  摘要：

  The anal secretions of skunks comprise several types of malodorous organosulfur compounds. The pungent metabolites are used defensively by skunks to repel threats posed by predators, and in many parts of the world, those perceived threats include humans and their pets. The extremely low thresholds for detection of the organosulfur metabolites make efforts to "de-skunk" people, animals, and clothing a process fraught with many challenges. The fungal-derived metabolite pericosine A (4) is a promiscuous yet stabile electrophilic compound that we propose is used by some fungi as a novel form of chemical defense. Our investigations have indicated that pericosine A readily reacts with skunk-spray secretions to transform them into odorless products. Mechanistic and computational studies suggested that pericosine A and its synthetic analogues react via S_N2'-type mechanisms with thiols and thioacetates under aqueous conditions to generate stable thioethers. Testing revealed that pericosine A did not cause skin or eye irritation and was highly effective at deodorizing skunk anal gland secretions when formulated to include adjunctive cosmetic ingredients.

  The first synthesis of (−)-pericosine E (6), a metabolite of the Periconia byssoides OUPS-N133 isolated originally from the sea hare Aplysia kurodai, has been achieved. Efficient and regioselective synthetic procedures for the synthesis of key intermediates, anti- and syn-epoxides 9 and 10, were developed using an anti-epoxidation of diene 12 with TFDO and a bromohydrination of 12 with NBS in CH3CN/H2O

  The synthesis of two diastereomers of pericosine A from (-)-quinic acid was achieved, thus enabling the confirmation of the relative configuration and elucidation of the absolute stereochemistry of cytotoxic natural product pericosine D assigned as methyl (3R,4R,5S,6R)-6-chloro-3,4,5-trihydroxy-1-cyclohexene-1-carboxylate.
