摘要:进行了氨基酸酪氨酸(1)和苯丙氨酸(2)样品的自然丰度氘核磁共振表征,以乙酰化的甲基酯4和6进行了检测,目的是通过这些方法鉴定羟基化对动物的贡献饮食中的1-苯丙氨酸(2)形成了1-酪氨酸(1),这是以前通过测定酚类delta(18)o值在相同样品上揭示的特征.这项研究还包括2中的苯甲酸(5)和1中的酪醇(7)的NMR检查,因为不同来源的酪氨酸样品的氘标记方式非常相似,但该研究基本上未能提供所需的信息,但表明两种氨基酸1和2的氘标记方式有显着差异.最相关的变化是关于ch(2)和ch位置的氘富集,这在自然衍生的两个氨基酸中是反向的.此外,尽管l-酪氨酸(1)的非对映位苄基氢原子似乎具有相同的氘富集度,但l-苯丙氨酸(2)中的(d / H)(3)(R)()>(d / H)(3)(S)().类似地,苯甲酸(5)显示出芳香族氘核的独立信号,这完全表明了天然或合成的衍生物.1和2侧链的氘标记方式暂时

标 题 :Synthesis of stable quinone and photoreactive ketone phosphoramidite reagents for solid phase synthesis of photoreactive-oligomer conjugates
发明人：FENSHOLDT JEF
权利人:EXIQON AS
摘要:Quinone phosphoramidite reagents as well as photoreactive ketone phosphoramidite reagents, such as anthraquinone phosphoramidite reagents and benzophenone phosphoramidite reagents were synthesized and used for the solid phase synthesis of photoreactive-oligonucleotide conjugates. These phosphoramidite reagents are stable, suitable for large-scale synthesis and designed for automated solid phase synthesis of oligomers terminating in a photoreactive moiety.

摘要:A method for synthesis of high quality colloidal nanoparticles using comprises a high heating rate process. Irradiation of single mode, high power, microwave is a particularly well suited technique to realize high quality semiconductor nanoparticles. The use of microwave radiation effectively automates the synthesis, and more importantly, permits the use of a continuous flow microwave reactor for commercial preparation of the high quality colloidal nanoparticles.

摘要:Protective groups which may be cleaved with an activatable deprotecting reagents are employed to achieve a highly sensitive, high resolution, combinatorial synthesis of pattern arrays of diverse polymers. In preferred embodiments of the instant invention, the activatable deprotecting reagent is a photoacid generator and the protective groups are DMT for nucleic acids and tBOC for amino acids. This invention has a wide variety of applications and is particularly useful for the solid phase combinatorial synthesis of polymers.
