two-step process. Reaction of 5,5′-dibromo-2,2′-dihydroxydiphenyl sulfide 1 and thiophosphoryl chloride in equimolar quantities in the presence of triethylamine as a base and DMAP as a catalyst in anhydrous toluene afforded the intermediate 6-chloro-2,10-dibromodibenzo[d,g][1,3,6,2]dioxathiaphosphocin 6-sulfide 2. Subsequent reaction of the monochloride 2 with sodium phenoxides/thiophenoxides afforded the
6位取代的2,10-二溴二苯并[ d,g ] [1,3,6,2]二氧杂硫磷6硫化物(3a-1)的合成已通过两步过程完成。在无水甲苯中以三乙胺为碱和DMAP为催化剂的存在下,以等摩尔量进行5,5'-二溴-2,2'-二羟基二苯硫醚1和硫代磷酰氯的反应,得到中间体6-氯-2,10-二溴二苯并[ d,g ] [1,3,6,2]二氧杂硫磷6硫化物2。一氯化物2与酚钠/噻吩氧化物的随后反应得到标题化合物。所有化合物对细菌和真菌均显示中等活性。
