one another, but unreactive with biopolymers and water, is challenging. Shown here are cobalt catalysts that react with alkenes under dilute, aqueous, buffered conditions and promote efficient cycloisomerization and formal Friedel–Crafts reactions. The constraining conditions of bioorthogonal chemistry are beneficial for reaction efficiency as superior conversion at low catalyst concentration is obtained
在稀溶液,缓冲水溶液条件下,在存在生物分子的情况下有效发生的制备反应可用于连接,肽合成以及多核苷酸合成和测序。然而,鉴定相互可反应但与生物聚合物和水不反应的官能团或试剂是具有挑战性的。此处显示的是钴催化剂,可在稀,水,缓冲条件下与烯烃反应,并促进有效的环异构化和正式的Friedel-Crafts反应。生物正交化学的约束条件对于反应效率是有利的,因为在低催化剂浓度下获得了优异的转化率,并且在稀薄条件下保持了合适的速率。
