Synthesis of 3,3,6,6-Tetramethyl-9-aryl-1,8-dioxo-1,2,3,4,5,6,7,8-octahydroxanthene in Aqueous Media

以氨基磺酸和十二烷醇硫酸钠(SDS)为复合催化剂,芳醛和5,5-二甲基-1,3-环己二酮为原料,于水中合成了3,3,6,6-四甲基-9-芳基-1,8-二氧代-1,2,3,4,5,6,7,8-八氢化氧杂蒽.方法具有操作简便,催化剂价廉易得、活性高、对环境友好、可回收重复使用等优点.

Synthesis of 3,3,6,6-tetramediyl-9-aryl-1,8-dioxo-1,2,3,4,5,6,7,8-octahydroxanthene from aromatic aldehyde and 5,5-dimethyl-1,3-cyclohexadione using NH2SO3H and SDS as the catalyst (10 mol%) in water was described. This method is manipulatively simple and the catalyst is low-cost, facile, high-active, environment-friendly and reusable.
