developed a convenient method for the synthesis of unsymmetrical disulfides of L-cysteine under mild conditions in good to excellent yields. The described method is based on the straightforward preparation of 5,5-dimethyl-2-thioxo-1,3,2-dioxaphosphorinane-2-sulfenyl bromide from readily available bis(5,5-dimethyl-2-thioxo-1,3,2-dioxaphosphorinan-2-yl) disulfide. The unsymmetrical disulfides can be obtained
我们开发了一种简便的方法,用于在温和条件下合成 L-半胱氨酸的不对称二硫化物,收率良好。所述方法基于从容易获得的双 (5,5-二甲基-2-硫代-1,3 ,2-dioxaphosphorinan-2-yl) 二硫化物。对于具有中性、碱性或酸性官能团的 L-半胱氨酸衍生物和硫醇,可以获得不对称二硫化物。
