synthesis and efficacy of preparing Cbz-VG-OMe (1) by thermolysis of alkyl and aryl homocysteine sulfoxides were surveyed. This investigation determined that aryl sulfoxide analogs were more effective for the reaction and that the 2-nitrophenyl analog 10f possessed a unique ability to syn eliminate at temperatures as low as 100 °C. The thermolysis of sulfoxide 10f was additionally discovered to occur
对烷基和芳基半胱氨酸亚砜热解制备Cbz-VG-OMe(1)的合成和功效进行了研究。这项研究确定了芳基亚砜类似物对于该反应更有效,并且2-硝基苯基类似物10f在低至100°C的温度下具有独特的合成消除能力。还发现亚砜10f的热分解在甲苯回流下发生,当添加乙酸钠时,可通过简单过滤沉淀的亚磺酸副产物12来获得高纯度的Cbz-VG-OMe(1)。这种温和的方案也用于合成VG二肽13 在从2-硝基苯基亚砜的烯烃和烯烃的一般合成中具有应用价值。
