  Enantioselective synthesis of cyclopropyl δ-lactonealdehydes and dodecyl-5-ene-1-yne-3-ol: advanced intermediates of solandelactone A and B

  摘要：

  A stereocontrolled synthesis of cyclopropyl delta-lactonealdehydes and dodecyl-5-ene-1-yne-3-ol is accomplished with predictable absolute stereochemistry via organocatalytic and catalytic asymmetric transfer hydrogenation reactions. The salient feature of this protocol is the genesis of chirality through an organocatalytic reaction and utilized for installing a critical bifunctional trans-cyclopropane motif, which is a key segment of every representative member of the oxylipin class of natural products such as solandelactone A and B.

  The total synthesis of solandelactones A and B is presented. The eastern cyclopropyl moiety was prepared following an exceptionally short chemoenzymatic approach whereas enantioselective synthesis of the western side-chain relied on the application of diastereomerically pure allyl boronates.

• Stereocontrolled asymmetric synthesis of syn-E-1,4-diol-2-enes using allyl boronates and its application in the total synthesis of solandelactone F

  The solandelactones A–H comprise a novel class of oxygenated fatty acids bearing an eight-membered lactone, transcyclopropane, and a 2-ene-1,4-diol subunit. The relative stereochemistry of the 1,4-diol subunit is anti in solandelactones A, C, E & G, and syn in solandelactones B, D, F & H. Having prepared one member of the solandelactones bearing anti stereochemistry (solandelactone E), we have targeted the syn series and developed methodology for the synthesis of enantioenriched syn-2-ene-1,4-diols. The methodology comprises asymmetric deprotonation of an alkyl 2,4,6-triisopropylbenzoate using sBuLi/sparteine, followed by addition of the α-lithiobenzoate to β-silyl vinyl boronic acid ethylene glycol ester. The boron-ate complex generated undergoes a 1,2-metallate rearrangement furnishing an intermediate allyl boronic ester which is trapped by an aldehyde in the presence of MgBr2 to furnish anti-β-hydroxyE-allylsilanes in good yields, high diastereoselectivity and high enantioselectivity. These sensitive products were oxidized using mCPBA to the corresponding epoxides and subsequently treated with acid to furnish syn-E-2-ene-1,4-diols (∼4 : 1 d.r.). Application of the methodology to appropriately functionalized aldehyde and ω-alkenyl 2,4,6-triisopropylbenzoate coupling partners, led to a short, highly selective route to solandelactone F (bearing a syn-E-2-ene-1,4-diol).

  Solandelactones A-H是一类新颖的含氧脂肪酸，具有八元内酯、反式环丙烷和2-烯-1,4-二醇子单元。在solandelactones A、C、E和G中，1,4-二醇子单元的相对立体化学为反式，而在solandelactones B、D、F和H中为顺式。我们已合成了具有反式立体化学的solandelactone E，并针对顺式系列开展研究，开发了合成富含对映体的顺式2-烯-1,4-二醇的方法。这一方法包括使用sBuLi/sparteine进行烷基2,4,6-三异丙基苯甲酸酯的非对称去质子化，随后将α-锂苯甲酸酯加入到β-硅基乙烯基硼酸乙二醇酯中。生成的硼酸盐复合物经历1,2-金属化重排，生成中间体烯丙基硼酸酯，在MgBr2存在下与醛反应，产生高产率、高立体选择性和高对映选择性的反式β-羟基E-烯丙基硅烷。这些敏感产物使用mCPBA被氧化为相应的环氧化物，并随后用酸处理生成顺式E-2-烯-1,4-二醇（约4:1的双对映体比）。将该方法应用于适当官能化的醛和ω-烯烃-2,4,6-三异丙基苯甲酸酯的偶联反应，得到了通向solandelactone F（具有顺式E-2-烯-1,4-二醇）的一条简短且高选择性路线。
• Total Synthesis of Solandelactones A, B, E, and F Exploiting a Tandem Petasis−Claisen Lactonization Strategy

  Solandelactones A, B, E, and F were synthesized using Nozaki-Hiyania-Kishi coupling of iododiene 13 with aldehydes 14 and 99 obtained by oxidation of alcohols 92 and 94. Key steps in the synthesis of 92 and 94 were (i) a Nagao asymmetric acetate aldol reaction of aldehyde 77 with thionothiazolidine 78 to set in place an alcohol that becomes the (7S) lactone center of solandelactones, (ii) a Simmons-Smith cyclopropanation of 80 directed by this alcohol, and (iii) Petasis methylenation of cyclic carbonate 90 in tandem with a Claisen rearrangement that generates the octenalactone portion of solandelactones. Synthesis of solandelactones A, B, E, and F confirmed their gross structure and absolute configuration at C7, 8, 10, and 14 but showed that alcohol configuration at C11 must be reversed in pairs, A/B and E/F, from the previous assignment made to these hydroid metabolites. Thus, solandelactones A and B are correctly represented by 2 and 1, respectively, whereas solandelactones E and F are 6 and 5. A biogenesis of solandelactones is proposed for these C(22) oxylipins that parallels a hypothesis put forward previously to explain the origin of C(20) cyclopropane-containing algal products.
