This paper reports on the synthesis and pharmacological activity of 6-aryl-4,5-dihydro-3(2H)-pyridazinone derivatives. The compounds exhibit an aggregationinhibiting action on human platelets in vitro and on rat platelets under ex vivo conditions, as well as a hypotensive action on rats. The strongest pharmacological effects were found with dihydropyridazinones, which have a 6-[p-[(chloroalkanoyl)amino]phenyl]
Provided is a compound capable of gelling various aqueous compositions containing salt, acid and the like.
An amphoteric ion-type basic amino acid derivative represented by the formula (1A):
wherein each substituent is as defined in DESCRIPTION, or a salt thereof.
Converting <i>gem</i>-Dimethyl Groups into Cyclopropanes via Pd-Catalyzed Sequential C−H Activation and Radical Cyclization

A novel route to the synthesis of cyclopropane derivatives is described. 1,1-Dimethyls in 2-(1,1-dimethylalkyl)dimethyloxazolines are first converted into 1,3-diiodide derivatives via Pd-catalyzed sequential C-H activation and then radically cyclized to provide 2-(1-alkylcylclopropyl)dimethyloxazolines. The use of EtOAc as a solvent is crucial for the diiodination of the functionalized substrates.
Pd(II)-Catalyzed Primary-C(sp<sup>3</sup>)–H Acyloxylation at Room Temperature

With the aid of a novel S-methyl-S-2-pyridyl-sulfoximine (MPyS) directing group (DG), the unactivated primary beta-C(sp(3))-H bond of MPyS-N-amides oxidizes at room temperature. The catalytic conditions are applicable to the diacetoxylation of primary beta,beta'-C(sp(3))-H bonds, and the carboxylic acid solvent is pivotal in the formation of the C-O bond. The MPyS-DG cleaves from the oxidation products and is recovered. This method provides convenient access to alpha,alpha'-disubstituted-beta-hydroxycarboxylic acids.
