We have developed convenient methods for the synthesis of functionalized unsymmetrical dialkyl disulfides under mild conditions in very good yields. The designed method is based on the reaction of (5,5-dimethyl-2-thioxo-1,3,2-dioxaphosphorinan-2-yl)-disulfanyl derivatives 1 with functionalized alkyl thiolate anions, generated in situ from thioacetates 2 and sodium methoxide or butylamine. The developed
我们已经开发了在温和条件下以非常高的收率合成功能化不对称二烷基二硫化物的便捷方法。设计的方法基于(5,5-二甲基-2-硫代氧杂1,3,2-二氧杂磷酰氨基-2-基)-二硫烷基衍生物1与硫代乙酸酯2和钠的原位生成的官能化硫代烷基磺酸盐的反应甲醇或丁胺。所开发的方法允许制备带有其他羟基,羧基,氨基,叠氮基,生物素或马来酰亚胺官能团的不对称二硫键。
