  • FLUORINATED SULFONATE ESTERS OF ARYL KETONES FOR NON-IONIC PHOTO-ACID GENERATORS
    申请人:International Business Machines Corporation
    公开号:US20180046077A1
    公开(公告)日:2018-02-15
    Non-ionic photo-acid generating (PAG) compounds were prepared that contain an aryl ketone group having a perfluorinated substituent alpha to the ketone carbonyl. The non-polymeric PAGs release a sulfonic acid when exposed to high energy radiation such as deep UV or extreme UV light. The photo-generated sulfonic acid has a low diffusion rate in an exposed resist layer subjected to a post-exposure bake (PEB) at 100° C. to 150° C., resulting in formation of good line patterns after development. At higher temperatures, the PAGs can also undergo a thermal reaction to form a sulfonic acid. The perfluorinated substituent provides improved thermal stability and hydrolytic/nucleophilic stability.
    非离子型光生酸(PAG)化合物被制备出来,它们含有一个含有全氟取代基的芳酮基团,该取代基位于酮羰基的α位置。这些非聚合PAGs在暴露于高能辐射,如深紫外或极紫外光时,会释放出磺酸。在100°C至150°C的后曝光烘烤(PEB)下,光生成的磺酸在暴露的抵抗层中具有较低的扩散速率,从而在开发后形成良好的线条图案。在较高温度下,PAGs也可以通过热反应形成磺酸。全氟取代基提供了改善的热稳定性和水解/亲核稳定性。

    A sequential NHC-amine catalytic cascade reaction has been developed to assemble aromatic aldehydes, trifluoroacetaldehyde ethyl hemiacetal and enals asymmetrically into CF3-substituted chiral γ-butyrolactone derivatives featuring vicinal quaternary and tertiary stereocenters. This approach incorporates a highly chemoselective intermolecular cross-benzoin reaction and a highly regioselective Michael-acetalization
    已经开发出顺序的NHC-胺催化级联反应,以将芳族醛,三氟乙醛乙基半缩醛和烯醛不对称地组装成具有邻位的季和叔立体中心的CF 3取代的手性γ-丁内酯衍生物。这种方法结合了高度化学选择性的分子间交叉安息香反应和高度区域选择性的迈克尔-乙缩醛级联反应。通过半缩醛中间体通过方便的有机转化可以轻松制备各种多功能的四氢呋喃支架。
  • Convenient Synthesis of .ALPHA.-Trifluoromethylated Acyloins from .ALPHA.-Hydroxy or .ALPHA.-Amino Acids.
    作者:Masami KAWASE、Setsuo SAITO、Teruo KURIHARA
    DOI:10.1248/cpb.48.1338
    日期:——
    acyloins (2 and 6) have been prepared from alpha-hydroxy acids (1), N-acylprolines (5) or N-acyl-N-alkyl alpha-amino acids (8) by novel transformation reactions with trifluoroacetic anhydride (TFAA) in the presence of pyridine. The former reaction of 1 could proceed through mesoionic 1,3-dioxolium-4-olates, whereas the latter two reactions of alpha-amino acids (5 and 8) could involve mesoionic 1,3-oxazolium-5-olates
    α-三氟甲基化酰基辅酶(2和6)是由α-羟基酸(1),N-酰基脯氨酸(5)或N-酰基-N-烷基α-氨基酸(8)与三氟乙酸酐( TFAA)在吡啶存在下。前者1的反应可以通过1,3-二氧恶唑鎓4-olates进行,而后两个α-氨基酸(5和8)的反应可能涉及1,3-二恶唑鎓5-olates。1与TFAA的反应在实际应用中显示出更大的潜力,这是因为起始材料易于使用且易于操作。

    A novel transformation of α-hydroxy acids to α-trifluoremethylated and α-perfluoroalkylated acyloins was efficiently realized by utilizing trifluoroacetic or perfluoroalkylcarboxylic anhydrides in the presence of pyridine, in which probable intermediates were meso-ionic 1,3-dioxolium-4-olates.
