  • The 3,4-dihydro-2H-pyran approach to (+)-milbemycin β<sub>3</sub>. Part 2. An improved synthesis of (2R,4S,6S,8R,9S)-2-[(5R)-(2E)-3-methyl-5-formyl-hex-2-en-1-yl]-8,9-dimethyl-4-(dimethyl-t-butylsilyloxy)-1,7-dioxaspiro[5.5]undecane

    A more efficient synthesis of the title compound (2), previously used in a total synthesis of (+)-milbemycin β3(1), is described. The key step in the sequence involves a nucleophilic cleavage of the oxirane (4) by the organocuprate derived from metallation of (2R,3S)-2,3-dimethyl-3,4-dihydro-2H-pyran (5).

  • Total synthesis of milbemycin E: synthesis of the C(11)–C(25) fragment
    作者:Patrick G. Steel、Eric J. Thomas
    DOI:10.1039/a605892b
    日期:——
    Treatment of 2-methylpropanal with the (E)-but-2-enyl(diisopinocampheyl)borane 9 prepared from (+)-α-pinene gives the anti- and syn-products 10 and 11, ratio 88∶12, from which the major anti-isomer 10 is separated by preparative GLC. Hydroboration–oxidation of its tert-butyldimethylsilyl ether 14 gives the primary alcohol 15 which has been converted into the bromide 16 and iodide 17. The propenyl(diisopinocampheyl)borane 23 prepared from (-)-α-pinene reacts with the aldehyde 22 prepared from (S)-malic acid to give the anti- and syn-1,3-diol derivatives 24 and 25, ratio 86∶14, and the anti-product 24 has been taken through to the epoxide 31. Sequential alkylation of 1,3-dithiane with the iodide 17 and the epoxide 31 gives the 2,2-dialkyl-1,3-dithiane 33 which is converted into the spiroacetal 4 by treatment with dilute aqueous hydrogen fluoride. After protection, ozonolysis gives the aldehyde 43 which has been condensed with the ylide 34 to give the α,β-unsaturated ester 44. This has been reduced and converted into the iodide 46 which has been used to alkylate the chiral oxazolidinone 39 to give the required C(11)–C(25) fragment 48 of milbemycin E 1 after reductive removal of the chiral auxiliary. This has been converted into the phosphonium salt 2 ready for Wittig coupling with the hydroxybutenolide 3 for the assembly of the milbemycin nucleus.
    将2-甲基丙醛与由(+)-α-松节油制备的(E)-丁-2-烯基(二异匹诺卡啉)硼烷9反应,得到反式和顺式产物10和11,比例为88∶12,其中主要的反式异构体10通过制备气相色谱法分离。其叔丁基二甲基氟硅醚14经过氢硼化–氧化反应得到初级醇15,进一步转化为溴化物16和碘化物17。由(-)-α-松节油制备的丙烯基(二异匹诺卡啉)硼烷23与由(S)-苹果酸制备的醛22反应,得到反式和顺式1,3-二醇衍生物24和25,比例为86∶14,反式产物24进一步转化为环氧化物31。1,3-二硫烷与碘化物17和环氧化物31进行顺序烷基化,得到2,2-二烷基-1,3-二硫烷33,通过稀氢氟酸处理转化为螺环醚4。保护后,臭氧解离反应得到醛43,随后与醇盐34缩合得到α,β-不饱和酯44。该酯经过还原反应转化为碘化物46,并用于烷基化手性噁唑烷酮39,得到米尔比霉素E 1所需的C(11)–C(25)片段48,经过还原去除手性辅助基后转化为磷盐2,为与羟基丁内酯3进行韦蒂格耦合以组装米尔比霉素核做好准备。
  • A difference CD method for determining absolute stereochemistry of acyclic 1,2,4-triols
    作者:Yuji Mori、Hiroshi Furukawa
    DOI:10.1016/0040-4020(95)00329-7
    日期:1995.6
    A general method based on difference circular dichroic (DIF CD) spectroscopy for assigning the absolute configuration of 1,2,4-triol is presented. Four possible stereoisomers of 6-heptene-1,2,4-triol were prepared and served as models to develop the procedure. The sign of the DIF CD Cotton effect is correlated to the absolute configuration of the C2 position.
    提出了一种基于差圆二向色(DIF CD)光谱法确定1,2,4-三醇绝对构型的通用方法。制备了四种可能的6-庚烯-1,2,4-三醇立体异构体,并将其用作开发该方法的模型。DIF CD棉花效应的迹象与C2位置的绝对构型相关。
  • Studies Aimed at the Total Synthesis of the Antitumor Antibiotic Cochleamycin A. An Enantioselective Biosynthesis-Based Pathway to the AB Bicyclic Core
    作者:Jiyoung Chang、Leo A. Paquette
    DOI:10.1021/ol0102592
    日期:2002.1.1
    [reaction: see text] A convergent, highly enantioselective synthesis of the fully functionalized AB sector of cochleamycin A is described. A pair of building blocks, crafted from L-malic and L-ascorbic acids, are conjoined in a manner that gives rise to an (E,Z,E)-1,6,8-nonatriene. On heating, the latter undergoes stereocontrolled intramolecular Diels-Alder cyclization via an endo transition state
    [反应:见正文]描述了完全功能化的球菌霉素A的AB区段的会聚,高对映选择性合成。一对由L-苹果酸和L-抗坏血酸制成的构件以产生(E,Z,E)-1,6,8-壬三烯的方式连接在一起。在加热时,后者通过内过渡态经历立体控制的分子内Diels-Alder环化。
  • Application of Stereoselective Ether Transfer to the Synthesis of Isotactic Polyethers
    作者:Kai Liu、Joseph W. Arico、Richard E. Taylor
    DOI:10.1021/jo100094d
    日期:2010.6.18
    the synthesis of a series of naturally occurring isotactic polymethoxy compounds. Ether transfer followed by a hydride workup enables simultaneous, diastereoselective production of two methoxy centers in a single step. High yields and diastereoselectivity are observed even in stereochemically rich, polyoxygenated systems. Direct generation of bis-methyl ether moieties from methoxymethyl ethers minimizes
    已经开发出一种高效、收敛的合成策略,可以合成一系列天然存在的全同立构多甲氧基化合物。醚转移和氢化物后处理能够在一个步骤中同时非对映选择性地生产两个甲氧基中心。即使在立体化学丰富的多氧化体系中也能观察到高产率和非对映选择性。从甲氧基甲基醚直接生成双甲基醚部分最大限度地减少了对典型保护基策略的需求和使用昂贵的甲基转移试剂。此外,同时生成末端初级碘化物可作为生成更高阶同类物的耦合伙伴。
