摘要:

发展了一种镍催化β-溴氨基酸酯与硫醚的交叉偶联反应,高效合成一系列新颖的半胱氨酸衍生物。 反应使用简单易得、结构稳定的β-溴氨基酸酯和二苯基二硫醚作为偶联前体,在四(三苯基膦)镍(0)/1,10-啡罗啉催化体系下,以中等至良好(58%~82%)的收率得到半胱氨酸衍生物。 此外,该反应采用“一锅法”通过一步合成的策略成功构建了C(sp3)—S键,并进一步拓展至C(sp3)—O/Se键的高效形成,实现了硒代半胱氨酸和丝氨酸衍生物的模块化合成。 反应条件温和、操作简单和底物兼容性好,为具有潜在药用价值的半胱氨酸、丝氨酸衍生物的合成提供新的方向。

Abstract:

A nickel-catalyzed cross-coupling reaction between readily available and structurally stable β-bromo amino acid esters and diphenyl disulfide has been developed, enabling the efficient synthesis of a series of novel cysteine derivatives. Employing the Ni(PPh34/1,10-phenanthroline catalytic system, the reaction proceeds smoothly under mild conditions, affording the target cysteine derivatives in moderate to good yields (58%~82%). Furthermore, this transformation utilizes a convenient one-pot procedure, successfully constructing the C(sp3)—S bond in a single step. The methodology has been successfully extended to the efficient formation of C(sp3)—O and C(sp3)—Se bonds, facilitating the modular synthesis of selenocysteine and serine derivatives. Featuring mild reaction conditions, operational simplicity, and excellent substrate compatibility, this strategy provides a new approach for synthesizing cysteine and serine derivatives with potential pharmaceutical value.
