Syntheses of 2-aryloxy/2-chloro ethoxy-2,3-dihydro-5-benzoyl-1H-1,3,2-benzodiaza-phosphole 2-oxides 3a–h were accomplished by reactions of equimolar quantities of 3,4-diaminobenzophenone (1) with various aryl/chloroethoxy phosphorodichloridates 2a–g and 2h in the presence of triethylamine at 50–60°C. Compounds 3i–k were prepared by reacting 3,4-diaminobenzophenone (1) with aryl thiophosphorodichloridates
2-芳氧基/2-氯乙氧基-2,3-二氢-5-苯甲酰基-1H-1,3,2-苯并二氮杂磷2-氧化物3a-h的合成是通过等摩尔量的3,4-二氨基二苯甲酮 (1) 与各种芳基/氯乙氧基二氯化磷酸酯 2a-g 和 2h,在三乙胺存在下,50-60°C。化合物 3i-k 通过 3,4-二氨基二苯甲酮 (1) 与芳基硫代磷酰二氯化物 2i-k 在类似条件下反应制备。它们通过 IR、1H、13C 和 31P NMR 光谱数据进行表征。其中一些产品具有显着的抗菌活性 © 2002 Wiley Periodicals, Inc.
