    摘要:
    与四嗪反应后,可从反式-环辛烯(TCO)进行生物正交裂解的烯丙基氨基甲酸酯。我们在本文中公开了该反应还可以裂解TCO酯,碳酸酯和令人惊奇的醚。机理研究表明,消除主要是由迅速消除的1,4-二氢哒嗪互变异构体的形成决定的,而较少取决于离去基团的性质。与广泛使用的p相反-氨基苄氧基连接基,可裂解芳族醚,但不裂解脂族醚,芳族,苄基和脂族TCO醚的裂解效率与氨基甲酸酯,碳酸酯和酯一样。快速解开血清中TCO掩盖的酪氨酸,然后酪氨酸酶氧化,证明了生物正交醚的释放。最后,酪氨酸解笼用于化学控制无酪氨酸培养基中的细胞生长。

    A visible light-sensitized benzylic sp3 CH fluorination protocol using dibenzosuberenone (5 mol %) and Selectfluor® is optimized for the direct functionalization of phenylalanine-like residues in short chain peptides. Amino acids, dipeptides, and tripeptides undergo benzylic fluorination with remarkable regioselectivity in the presence of protected basic, acidic, and nonpolar side chains (including

  • Photorelease of tyrosine from a-carboxy-6-nitroveratryl (aCNV) derivatives
    作者:Alexander G. Russell、Matthew J. Sadler、Helen J. Laidlaw、Agustín Gutiérrez-Loriente、Christopher W. Wharton、David Carteau、Dario M. Bassani、John S. Snaith
    DOI:10.1039/c2pp05320a
    日期:2012.3
    The synthesis of photolabile tyrosine derivatives protected on the phenolic oxygen by the α-carboxy-6-nitroveratryl (αCNV) protecting group is described. The compounds undergo rapid photolysis at wavelengths longer than 300 nm to liberate the corresponding phenol in excellent yield (quantum yield for the deprotection of tyrosine = 0.19). Further protection of caged tyrosine is possible, yielding N-Fmoc protected derivatives suitable for direct incorporation of caged tyrosine in solid-phase peptide synthesis.

    作者:Mark A. R. de Geus、G. J. Mirjam Groenewold、Elmer Maurits、Can Araman、Sander I. van Kasteren

    The inverse electron-demand Diels–Alder (IEDDA) pyridazine elimination is one of the key bioorthogonal bond-breaking reactions. In this reaction trans-cyclooctene (TCO) serves as a tetrazine responsive caging moiety for amines, carboxylic acids and alcohols. One issue to date has been the lack of synthetic methods towards TCO ethers from functionalized (aliphatic) alcohols, thereby restricting bioorthogonal
    逆电子需求的Diels–Alder(IEDDA)哒嗪消除是关键的生物正交键断裂反应之一。在该反应中,反式-环辛烯(TCO)作为胺,羧酸和醇的四嗪响应笼蔽部分。迄今为止的一个问题是缺乏从官能化的(脂族)醇制备TCO醚的合成方法,从而限制了生物正交的利用。开发了两种新型试剂,可控制顺式-环辛烯(CCO)醚的形成,然后进行优化的光化学异构化以获得TCO醚。该方法以大肠杆菌中lac操纵子系统的受控生物正交激活为例 使用TCO醚修饰的碳水化合物诱导剂。
  • Photochemical trifluoromethylation of tyramine and L-tyrosine derivatives
    作者:Kenneth L. Kirk、Mazakazu Nishida、Shozo Fujii、Hiroshi Kimoto
    DOI:10.1016/s0022-1139(00)82410-0
    日期:1992.11
    Ultraviolet irradiation (254 nm) of methanolic solutions of trifluoromethyl iodide (CF3I) in the presence of side-chain-protected tyramine and L-tyrosine results in trifluoromethylation of the aromatic ring. The presence of an amine base to neutralize HI formed during the reaction is essential. The electrophilic trifluoromethyl radical preferentially attacks the ring ortho to the phenolic group, and 3-trifluoromethyltyramine
    在侧链保护的酪胺和L-酪氨酸的存在下,对三氟甲基碘(CF 3 I )的甲醇溶液进行紫外线照射(254 nm)导致芳环的三氟甲基化。胺碱的存在对中和反应过程中形成的HI是必不可少的。亲电子三氟甲基自由基优先攻击邻位至酚基的环,得到3-三氟甲基酪胺和3-三氟甲基-L-酪氨酸衍生物,产率分别为27%和33%。
