Some new 1,3,4-triazolo-, 1,3,4-oxadiazolo-, 1,3,4-thiadiazol-, and pyrazolo-3,4-dimethylphenyl-1(2H)-oxo-phthalazine derivatives were synthesized and identified by IR, 1H NMR, MS and elemental analysis. Most of the newly synthesized products were tested for their anti-inflammatory activities. Among them, compounds 11, 17b, 20, 21 and 22 are active compare to the activity of indomethacin®.
合成了一些新的1,3,4-三唑-,1,3,4-恶二唑-,1,3,4-噻二唑-和吡唑并3,4-二甲基苯基-1(2 H)-氧代-邻苯二嗪衍生物并通过IR,1 H NMR,MS和元素分析鉴定。测试了大多数新合成的产品的抗炎活性。其中,化合物11,17B,20,21和22是活动的比较吲哚美辛的活性®。

hitherto unknown reaction of N-aminophthalimide (1) with aromatic hydrocarbons under Friedel-Crafts conditions. The reaction of N-aminophthalimide with Grignard reagents presents another convenient method for the synthesis of 4-alkyl or 4-arylphthalaz-1-ones.
Rhodium(III)‐catalyzed selective C–H bond mono‐/bialkynylation of 4‐aryl phthalazin‐1(2H)‐one was developed. The silver salt AgSbF6 are demonstrated to play a vital role in promoting the bialkynylation reactions. Additionally, 6‐aryl pyridazin‐3(2H)‐one scaffold is amenable to the selective monoalkynylation and sequential bialkynylation, respectively. The present alkynylation strategy is simple, efficient
