  2-苯磺酰基环醚与碳亲核试剂的取代反应

  摘要：

  使用多种碳亲核试剂研究了2-苯磺酰基环醚的直接取代。这些亲核试剂包括有机锌试剂（衍生自芳基，乙烯基和炔基格利雅试剂）或甲硅烷基烯醇醚，甲硅烷基乙烯酮缩醛，烯丙基硅烷和三甲基甲硅烷基氰化物。使用6-取代的砜观察到形成反式产物的一般选择性。

• Stereoselective Syntheses of α-Substituted Cyclic Ethers and<i>syn</i>-1,3-Diols
  作者：Koichi Homma、Haruhiro Takenoshita、Teruaki Mukaiyama

  DOI：10.1246/bcsj.63.1898

  日期：1990.7

  system of antimony pentachloride, chlorotrimethylsilane and tin(II) iodide, α-substituted cyclic ethers are stereoselectively prepared from lactones by successive treatment with 1-(t-butyldimethylsiloxy)-1-ethoxyethene and silyl nucleophiles such as triethylsilane, allyltrimethylsilane and trimethylsilyl cyanide. These catalysts also promote the reaction of γ-, δ-, and e-trimethylsiloxy carbonyl compounds

  在催化量的三苯基甲基六氯锑酸盐或五氯化锑、氯三甲基硅烷和碘化锡(II)的催化体系存在下，通过1-(叔丁基二甲基甲硅烷氧基)-1-连续处理，由内酯立体选择性地制备α-取代环醚乙氧基乙烯和甲硅烷基亲核试剂，例如三乙基硅烷、烯丙基三甲基硅烷和三甲基硅烷基氰化物。这些催化剂还促进 γ-、δ-和 e-三甲基甲硅烷氧基羰基化合物与甲硅烷基亲核试剂的反应，从而形成 α-取代的环醚。前一种程序有效地应用于 (-)-顺式玫瑰氧化物和 (cis-6-methyltetrahydro-2-pyranyl) 乙酸（一种麝猫香的成分）的短程合成。此外，syn-1,3-二醇也由内酯类似物立体选择性地制备，

  Five–seven membered cyclic ethers are prepared by one-pot procedure in good yields from γ-, δ-, and e-siloxy carbonyl compounds, respectively, on treatment with silyl nucleophiles (triethylsilane, allyltrimethylsilane, trimethylsilyl cyanide, etc.) in the presence of a catalytic amount of trityl hexachloroantimonate, or a catalyst system of antimony pentachloride, chlorotrimethylsilane and tin (II)

• Masked lithium bishomoenolates: useful intermediates in organic synthesis
  作者：Diego J. Ramon、Miguel Yus

  DOI：10.1021/jo00012a012

  日期：1991.6

  The lithiation of the chloro ketals 9 with lithium naphthalenide at -78-degrees-C led to the corresponding masked lithium bishomoenolates 4, which are stable species under these conditions and react with different electrophilic reagents (H2O, D2O, i-PrCHO, PhCHO, MeCOEt, (activated CH2)4CO, (activated CH2)5CO, (activated CH2)7CO, PhCOMe, c-C3H5COPh, PhCN, HCONMe2, PrCO activated N(CH2)4, PhCO activated N(CH2)4, PhCOCl, EtOCOCl, PhCHNPh, and (PhCH2S)2) to give, after hydrolysis with water, the corresponding bifunctionalized compounds 10a-22a, 10b-22b, and 10c-15c. When alkyl halides were used as electrophiles the reaction failed. In the presence of a catalytic amount of the complex CuBr.Me2S, the same reaction with alpha,beta-unsaturated ketones (methyl vinyl ketone or 2-cyclohexanone) yielded the expected products of a 1,4-addition 25a-c and 26b. The deprotection of the masked carbonyl group was easily done by treatment with 2 N hydrochloric acid in THF, so as examples, compounds 27a-29a, 30b, 31b, 32c, and 33c were isolated. The transformation of hemiacetals of the type 27a into substituted tetrahydropyrans was carried out by means of compounds of the type R3SiNu (Nu = H, allyl, CN) in the presence of BF3, so products 34a-41a, 42b, and 43b were prepared. Finally, the in situ oxidation of the deprotected products of the type 27a-arising from the reaction of bishomoenolate 4a with carbonyl compounds-with Jones reagent (for ketones derivatives) or PCC (for aldehydes derivatives) led to the corresponding delta-lactones 44-57.
