described. A sequence of ruthenium-catalyzed cross metathesis and rhodium-catalyzed hydrogenation of nonproteinaceous allylglycine derivatives has been developed to achieve high-yielding and unambiguous formation of diaminosuberic acid derivatives. Allylglycine derivatives readily undergo ruthenium-catalyzed metathesis and hydrogenation to yield diaminosuberic acid derivatives in near quantitative yield
描述了一种促进区域选择性形成胱氨酸的多个双卡巴等位基因的方法。已经开发了一系列钌催化的交叉复分解和铑催化的非蛋白质烯丙基甘氨酸衍生物的氢化反应,以实现高产率和毫不含糊地形成二氨基硫酸衍生物。烯丙基甘氨酸衍生物容易进行钌催化的复分解和氢化,以接近定量的产率产生二氨基丁二酸衍生物。在相同的实验条件下,发现异戊烯基甘氨酸分别对Grubbs和Wilkinson催化的复分解和氢化均呈惰性,但很容易通过与Z的交叉复分解活化进行复分解。-丁烯。随后经易位形成的巴豆基甘氨酸衍生物的交叉易位,然后氢化,以优异的产率得到了第二种二氨基丁二酸衍生物。
