  Importance of the Methyl Group at C(10) of Squalene for Hopene Biosynthesis and Novel Carbocyclic Skeletons with 6/5 + 5/5 + (6) Ring System(s)

  摘要：

  [GRAPHICS]Incubation of (6E,10E,14E,18E)-2,6,10,19,23-pentamethyl-tetracosa-2,6,10,14,18,22-hexaene with Alicyclobacillus acidocaidarius hopene cyclase afforded four products having two types of carbocyclic skeletons, i.e., two hopane products and two products having an unprecedented carbocyclic skeleton of 6/5 + 5/5 +6 pentacyclic and 6/5 + 5/5 tetracyclic ring systems. The former two hopane skeletons were formed from the bioconversion of C(15)-desmethylsqualene and the latter two skeletons from that of C(10)-desmethylsqualene.

  rac-Hippospongic acid A of the reported structure 1 and the revised structure 2 were synthesized. The synthetic strategy of these compounds consists of homologation of (2E,6E,10E)-geranylgeraniol and (2E,6E)-farnesol, respectively, Wadsworth–Emmons reaction, and cyclization to form the tetrahydropyran ring bearing an α-methylene group on the carboxylic moiety. Spectral comparisons of the synthetic compounds 1, 2 and the natural product suggested that hippospongic acid A bears the structure of 2.

  two diterpene cyclases from streptomycetes—one with an unknown product that was identified as the spirocyclic hydrocarbon spiroviolene and one with the known product tsukubadiene—were investigated in detail by isotope labeling experiments. Although the structures of the products were very different, the cyclization mechanisms of both enzymes proceed through the same initial cyclization reactions, before

  Lanosterol synthase catalyzes the polycyclization reaction of (3S)‐2,3‐oxidosqualene (1) into tetracyclic lanosterol 2 by folding 1 in a chair‐boat‐chair‐chair conformation. 27‐Nor‐ and 29‐noroxidosqaulenes (7 and 8, respectively) were incubated with this enzyme to investigate the role of the methyl groups on 1 for the polycyclization cascade. Compound 7 afforded two enzymatic products, namely, 30‐norlanosterol

  羊毛甾醇合酶通过将1折叠成椅子-椅子-椅子-构象，催化（3 S）-2,3-氧化角鲨烯（1）变成四环羊毛甾醇2的多环化反应。将27-Nor-和29-Noroxidosqaulenes（分别为7和8）与该酶一起孵育，以研究1上的甲基在多环化级联反应中的作用。化合物7得到两个酶产物，即30-norlanosterol（12）和26-normalabaricatriene（13 ; 12 / 139：1），分别通过正常的椅子-椅子-椅子构造和非典型的椅子-椅子-构造构造而成。化合物8得到两个产物14和15（14 / 15 4：5），这是由正常的和不寻常的polycyclization通路通过一个椅子椅的船形椅式构象中分别产生，。值得注意的是，B形圈的麻花船结构被改为15代时在能量上很受青睐的椅子结构。令人惊讶的是14和15由一个新颖的6,6,6,6-稠合的四环系统组成，因此不同于6,6,6,5-稠
