of readily available amino acids, which is not only an oxygen nucleophile but also a nitrogen nucleophile, in palladium-catalyzed allylic substitution is realized under mild conditions. The chemoselectivity and multiple allylation are controlled by adjusting the reaction conditions. This represents the first example of this convenient access to valuable N,O-diallylated amino acids. Under the title conditions
在温和条件下实现了在钯催化的烯丙基取代中利用容易获得的氨基酸,它不仅是氧亲核试剂,而且是氮亲核试剂。通过调节反应条件来控制化学选择性和多重烯丙基化。这代表了这种方便地获得有价值的N,O-二烯丙基化氨基酸的第一个例子。在标题条件下,一系列氨基酸(α-、β-、γ-)和二肽可以很容易地转化为相应的烯丙基产物,具有优异的产率(67 个实例,高达 99% 的产率)以及良好的功能性群体容忍度。
