日期:2006.10.1
The use of catalyticmetalcarbene methodology with diazoacetates for the construction in high yield of polyether macrocycles having ring sizes greater than 25 has been achieved by preventing access to γ-C−H positions for intramolecular insertion. Cyclopropanation is the exclusive outcome of reactions performed with dirhodium(II) catalysts, and product yields of greater than 70% are obtained without

BAs on peptidechains. In this study, a “boronhotspot“ based on the 3‐hydroxyquinolin‐2(1H)‐one scaffold was developed and upon installation on a peptide N‐terminal cysteine, enables the site‐selective formation of iminoboronates with 2‐formyl‐phenyl boronic acids (Ka of 58128±2 m−1). The reaction is selective in the presence of competing lysine ϵ‐amino groups, and the resulting iminoboronates, displayed
硼酸(BAs)是设计动态材料的一种有前途的生物共轭功能,因为它们可以与对不同pH,ROS,碳水化合物和谷胱甘肽水平响应的氧/氮亲核试剂建立可逆的共价键。然而,这些键的动力学性质也限制了对生物缀合的稳定性和位点选择性的控制,这最终导致在生理条件下稳定性差的异质缀合物。在这里,我们公开了一种在肽链上安装BA的新策略。在这项研究中,开发了基于3-羟基喹啉-2(1 H)-one支架的“硼热点”,并将其安装在肽的N端半胱氨酸上,能够与2-甲酰基选择性地形成亚氨基硼酸酯。苯硼酸(K a58128±2 m -1)。在竞争性赖氨酸ϵ-氨基存在下,该反应具有选择性,所得的亚氨基硼酸酯在缓冲溶液中显示出改善的稳定性,在谷胱甘肽存在下具有可裂解的特性。一旦开发完成,该方法就可用于制备具有层粘连蛋白片段的可裂解的荧光偶联物,从而可以验证67LR受体是否是将货物运送至癌症HT29细胞的靶标。
