    As a model study on the synthesis of natural products possessing an eight-membered cyclic ether or amine framework such as laurencin (1) and FR900482 (6), two kinds of 2-benzyl oxacyclooctanones (7 and 8) and 2-methyl azacyclooctanones (9 and 10) were synthesized from the corresponding twelve-membered lactam sulfoxides (49-52) by applying our general method for medium-ring ketone synthesis. The corresponding lactam sulfides were readily prepared from the linear ω-tosyl carboxylic acids containing on oxygen atom (11 and 12) or methylcarbamate group (13 and 14) by condensation with 2-cyanoethyl 2-N-methylaminophenyl sulfide followed by alkylation.
    作为月桂苷(1)和 FR900482(6)等具有八元环醚或胺框架的天然产物的合成模型研究,我们采用中环酮合成的一般方法,从相应的十二元内酰胺硫化物(49-52)合成了两种 2-苄基氧杂环辛酮(7 和 8)和 2-甲基氮杂环辛酮(9 和 10)。相应的内酰胺硫化物是由含有氧原子(11 和 12)或甲基氨基甲酸酯基团(13 和 14)的线性ω-对甲苯磺酰基羧酸与 2-氰乙基 2-N-甲基氨基苯基硫醚缩合,然后烷基化而容易制备的。

    The bicyclo [5.3.1] undecanone 5 corresponding to the A and B rings in taxane diterpenes was synthesized from β-ionone.Reduction of the tosylhydrazone 11 with catecholborane afforded the trisubstituted olefin 12 having trans substituents at the C-1 and C-7 positions.The requisite cis-arrangement of these substituents for eight-membered ring formation was induced by epimerization of the aldehyde 13 to give the bicyclic hemiacetal 14.The lithium diisopropylamide-promoted intramolecular cyclization of the twelve-membered lactam sulfoxide 32 proceeded quite smoothly, affording the eight-membered keto sulfoxide 33 in quantitative yield.
    用邻苯二酚硼烷还原对甲苯腙 11,得到了在 C-1 和 C-7 位具有反式取代基的三取代烯烃 12。在二异丙基酰胺锂的促进下,十二元内酰胺亚砜 32 的分子内环化进行得相当顺利,得到了八元酮亚砜 33,产率为定量。
  • Studies on Taxane Synthesis. III. Stereocontrolled Synthesis of a Twelve-Membered Lactam Sulfide as a Precursor of 4,8,11,11-Tetramethyl-3-oxobicyclo(5.3.1)undec-8-ene.

    Stereocontrolled synthesis of two twelve-membered lactam sulfides 37 and 38 as precurors of 8, 11, 11-trimethyl-3-oxobicyclo[5.3.1]undec-8-enes constituting the A and B rins of taxane-diterpenes was achieved.The keystep involves a Diels-Alder reaction of maleic anhydride and the E-diene 18 for introduction of the requisite cis arrangement of substitutions at the C-1 and C-7 positions.The resulting adduct was converted exclusively into the lactone 21b in five steps : 1) hydrolysis, 2) iodo-lactonization, 3) BH3 reduction, 4) Zn reduction, 5) methylation.The benzyl group of 26 could be selectively removed by heating with Raney Ni(W-2) in EtOH in nearly quantitative yield without hydrogenation of the double bond.
    实现了两个十二元内酰胺硫化物 37 和 38 的立体控制合成,它们是构成紫杉烷-二萜 A 和 B 环的 8、11、11-三甲基-3-氧代双环[5.3.1]十一碳-8-烯的前体。关键步骤是马来酸酐和 E-二烯 18 发生 Diels-Alder 反应,在 C-1 和 C-7 位置引入必要的顺式排列取代:用 Raney Ni(W-2) 在 EtOH 中加热,可以选择性地去除 26 的苄基,几乎可以得到定量的收率,而不需要双键氢化。

    A synthesis of the taxane ring system is described. The A-ring moiety 5, containing the carbons for construction of the B-ring, was prepared from Wieland-Miescher ketone via Beckmann fragmentation of the oxime 10. The B-ring was formed by means of 12-membered lactam-sulfoxide ring contraction. The formation of the C-ring was carried out by aldol condensation of the resulting AB-ring moiety 3 followed by intramolecular pinacol coupling to give the tricyclic diol 23.
    本文介绍了一种紫杉烷环系统的合成方法。A 环分子 5 含有用于构建 B 环的碳原子,由 Wieland-Miescher 酮通过肟 10 的贝克曼破碎法制备而成。B 环是通过 12 元内酰胺-亚砜环收缩形成的。C 环的形成是通过 AB 环分子 3 的醛醇缩合,然后通过分子内频哪醇偶联得到三环二醇 23。

    Two types of tetramethylbicyclo [5.3.1] undec-8-enes 2 and 3 were synthesized from oc-ionone as a model for taxane synthesis.Introduction of the requisite cis-arrangement of substituents at the C-1 and C-7 positions was carried out by catalytic hydrogenation of the α, β-unsaturated ketone 12. Treatment of the hydroxy ester 27 and 16 with diethyl azodicarboxylate and triphenylphosphine led to regioselective dehydration giving 33 and 43, respectively.Intramolecular cyclization of 41 and 49 with lithium diisopropylamide followed by reductive desulfurization with Na-Hg produced the eight-membered ring ketones 2 and 3, respectively, in good yields.
    通过对 α、β-不饱和酮 12 进行催化氢化,在 C-1 和 C-7 位置引入了必要的顺式排列取代基。用二异丙基酰胺锂对 41 和 49 进行分子内环化,然后用 Na-Hg 进行还原脱硫,分别生成了八元环酮 2 和 3,产率良好。
