This disclosure describes novel substituted aralkanamidobenzoic acids and analogs thereof. These compounds are useful pharmaceutical agents for ameliorating atherosclerosis by inhibiting the formation and development of atherosclerotic lesions in the arterial wall of mammals.
Diastereoselective Pd(II)-Catalyzed sp<sup>3</sup>C–H Arylation Followed by Ring Opening of Cyclopropanecarboxamides: Construction of<i>anti</i>β-Acyloxy Carboxamide Derivatives
diastereoselective Pd(OAc)2-catalyzed, bidentate ligand-directed sp3 C–H activation/arylation followed by ring opening of cyclopropanecarboxamides, which were assembled from cyclopropanecarbonyl chlorides and bidentate ligands (e.g., 8-aminoquinoline and 2-(methylthio)aniline), has been investigated. The treatment of various cyclopropanecarboxamides with excess amounts of aryl iodides in the presence of the Pd(OAc)2

hydroarylation with less reactive benzene to give cis-cinnamic acid in good yield. The hydroarylation with toluene gave a higher yield of hydroarylation products than that with benzene and resulted in ortho/para orientation with an almost statistical ratio, suggesting that the result is very close to that of the Friedel-Crafts alkylation with methyl bromide or p-nitrobenzyl chloride. Hydroarylation of propiolic
2-dioxazol-5-ones to form dihydroquinoline-2-ones in excellent yields with excellent regioselectivity via a formal intramolecular arene C(sp2)–Hamidation. The reactions of the 2- and 4-substituted aryl dioxazolones proceeds initially through spirolactamization via electrophilic amidation at the arene site, which is para or ortho to the substituent. A Hammett correlation study showed that the spirolactamization

also radical precursors. Classic transition-metal-catalyzed and photochemical decarboxylation have shown their excellent site selectivity in radical chemistry. However, electrochemical decarboxylation with a long history hasn't got enough attention in recent years. In this work, the electrochemical oxidativedecarboxylation and 1,2-aryl migration of 3,3-diarylpropionic acids have been introduced to construct
