A new, mild method of synthesis of 2‐hydroxyphenyl vinyl sulfones from 4,4‐dioxo‐2,3‐dihydrobenzo[b][1,4]oxathiine derivatives is described. The products were further modified in situ, either by Michael addition of nucleophiles or by reaction of the 2‐hydroxy group with an electrophile. The method can be utilized to immobilize proteins on a suitable support, or for other similar applications, as generation
描述了一种由4,4-二氧代-2-3,二氢苯并[ b ] [1,4]草嘌呤衍生物合成2-羟苯基乙烯基砜的温和新方法。通过亲核试剂的迈克尔加成反应或2-羟基与亲电试剂的反应,对产物进行原位修饰。该方法可用于将蛋白质固定在合适的载体上,或用于其他类似的应用,因为乙烯基砜的产生总是伴随着酚盐阴离子的形成,该酚盐阴离子可用于将乙烯基砜原位键合到合适的载体上。
