with p-toluenesulfinic acid allows the efficient preparation of unsymmetrical arylsulfonyl bisbenzazole derivatives. Substitution of the arylsulfonyl group from these adducts using sodium borohydride leads to the corresponding bisbenzazoles. Functional implementation of the bisbenzazole system can be achieved using Grignard and Reformatsky reagents.
两种不同的苯并恶唑化合物与对甲苯磺酸的三组分偶联可以有效地制备不对称的芳基磺酰基双苯并唑衍生物。使用硼氢化钠从这些加合物取代芳基磺酰基得到相应的联苯并恶唑。可以使用Grignard和Reformatsky试剂实现对苯并恶唑系统的功能实施。
