摘要:该发明使用多光束阴极射线管(6)来书写具有最大数据速率和写入速度降低因子等于同时操作光束数量的电视类型光栅或帧.为了克服图像中的过度斜率(图4A),采用了分步偏转(图4B),使得大部分垂直偏转发生在特定水平扫描完成之后,并在连续扫描开始之前.通过使用光学传输滤光器(20)进一步增加扫描速度,该滤光器能够选择性地传输阴极射线管屏幕发出的分离颜色,其中滤光器的一部分(20A)可以设置为传输颜色序列中的下一个颜色,而滤光器的其余部分(20B)正在传输当前显示的颜色.

标题 :Solid support for the synthesis of 3′-amino oligonucleotides
发明人：LEUCK MICHAEL; WOLTER ANDREAS
权利人:SIGMA ALDRICH CO
摘要:The present invention discloses novel methods and solid supports for the synthesis of 3′-amino oligonucleotides. The novel supports are based on an unsubstituted or ring-substituted hydroxymethylbenzoyl linker element wherein the hydroxymethyl group is esterified to a solid phase bound carboxylic acid and the carbonyl group is linked to an amino alcohol as an amide. Oligonucleotides are conveniently synthesized on the novel supports with no modifications in the standard phosphoramidite synthesis scheme. The ester function of the support is cleaved under the alkaline deprotection conditions for oligonucleotides to provide a free hydroxymethyl group that aids in the release of the 3′-amino oligonucleotide products with a free amino group through neighbor group participation. The free amino group of the oligonucleotides is available for further conjugation reactions to haptens, reporter groups, surfaces or other small molecules or biomolecules. The methods provided are particularly mild, do not require any modifications in standard protocols for the synthesis and deprotection of oligonucleotides, provide the 3′-amino oligonucleotides free of side products and do not introduce chiral centers to the oligonucleotides.

摘要:The subject invention relates to a process for the synthesis of highly active binary metal fluoride system for the fluorination of aromatic compounds. Fluorinated aromatic compounds are valuable synthons for the chemical synthesis of pharmaceutical drugs and novel polymers. Fluorobenzene is used to control carbon content in steel manufacturing, is an intermediate for pharmaceuticals, pesticides and other organic compounds. Fluorobenzene is typically produced by the reaction of aniline and sodium nitrite in the presence of hydrogen fluoride. The present invention relates to a process for the synthesis of highly active binary metal fluoride system consists of copper (II) fluoride and aluminum (III) fluoride for the fluorination of aromatic compounds in gas phase and recycling of the reagent, in situ, using O 2 and HF.
