Efficient Aromatization of 4,5-Dihydro-3(2H)-Pyridazinones Substituted at 5 Position by Using Anhydrous Copper (II) Chloride
摘要:
An efficient conversion of 5-substituted-4,5-dihydro-3(2H)-pyridazinones into their corresponding dehydrogenated derivatives was achieved by treatment with anhydrous copper(II) chloride in acetonitrile.

evaluated in vitro for inhibition of plateletaggregation induced by adenosine 5'-diphosphate (ADP), thrombin and collagen. All the tested compounds (except 8 and 9) inhibited plateletaggregation in a dose-dependent manner. The IC50 of the most active substance, compound 2b, was around 60 microM against ADP and collagen as inducers. The inhibition of plateletaggregation caused by test compounds was dependent
