  • Photoacid generator, chemically amplified resist composition including the same, and associated methods

    A photoacid generator represented by Formula 1 or Formula 2: wherein R 1 , R 2 , and R 3 are each independently a C1-C10 alkyl group, X is a C3-C20 alicyclic hydrocarbon group forming a ring with S + , and at least one CH 2 group in the alicyclic hydrocarbon group may be replaced with at least one selected from the group consisting of S, O, NH, a carbonyl group, and R 5 —S + A − , where R 5 is a C1-C10 alkyl group, and A − is a counter-ion.

  • The asymmetric synthesis of terminal aziridines by methylene transfer from sulfonium ylides to imines
    作者:Sarah A. Kavanagh、Alessandro Piccinini、Stephen J. Connon
    DOI:10.1039/c3ob27271k
    日期:——
    simple salt derived from (2R,5R)-2,5-diisopropyl thiolane could mediate asymmetric methylene transfer to a range of imines with uniformly excellent yields with 19–30% ee. Since this is a similar level of enantiomeric excess to that obtained using these same salts in epoxidation chemistry, it was concluded that if more bulky sulfonium salts could be devised which were resistant to decomposition under
    已经开发了一种新的基于叶立德的方案,用于通过亚甲基转移进行亚胺的不对称叠氮化,涉及使用简单的手性sulf盐和有机强碱。一项系统的研究确定了三异丙基苯基磺酰亚胺为该工艺的最佳底物。出乎意料的是,在C-2和C-5处掺入大体积醚的受阻C 2对称磺酰基盐(以前在相应的环氧化化学中有用)在这些叠氮化反应中通过竞争性消除途径分解。在优化的条件下,发现从(2 R,5 R)-2,5-二异丙基硫杂环戊烷可以介导不对称的亚甲基转移到一系列亚胺上,其ee均具有优异的收率,其ee含量为19%至30%。由于这与在环氧化化学中使用这些相同盐获得的对映体过量水平相似,因此得出结论,如果可以设计出更大体积的sulf盐,在反应条件下耐分解,则可以通过亚甲基转移形成高度对映选择性的氮丙啶可能的。
  • Catalytic (Asymmetric) Methylene Transfer to Aldehydes
    作者:Alessandro Piccinini、Sarah A. Kavanagh、Paul B. Connon、Stephen J. Connon
    DOI:10.1021/ol902816w
    日期:2010.2.5
    An investigation into the poor activity of sulfides as catalysts for sulfonium-ylide-mediated methylene transfer to aldehydes has indicated that ylide formation is the problematic catalytic cycle step. Alkylation with traditional electrophiles does not proceed with sufficient efficiency to allow the sulfide to be used catalytically. Methyl triflate rapidly alkylates cyclic thiolanes under mild conditions, allowing their use in efficient aldehyde epoxidation reactions (in conjunction with phosphazene bases) at loadings as low as 10 mol %.
  • Synthesis of <i>gem</i>-Difluorinated Hydroxypyrrolidines

    A method for the synthesis of 3-hydroxy-4,4-difluoropyrrolidines from α,α-difluoro-β-bromoketones is described. The reaction involves methylenation of the carbonyl group with tetrahydrothiophenium ylide followed by coupling with primary amines.
