Abstract Twenty-five amides were synthesized in almost quantitative yields by microwave-assisted condensation of arylacetic acids and 2-aryl-ethylamines undersolventlessconditions. The N-arylethyl-arylacetylamides are intermediates of the corresponding isoquinoline derivates. Supplemental materials are available for this article.

A range of secondary and tertiary phenylacetamides undergo oxidative homodimerization to afford biaryls. The reaction proceeds under palladium catalysis in the presence of a copper cocatalyst and oxygen and is most effective for electron-rich substrates.
Copper(<scp>ii</scp>)-catalyzed and acid-promoted highly regioselective oxidation of tautomerizable C(sp<sup>3</sup>)–H bonds adjacent to 3,4-dihydroisoquinolines using air (O<sub>2</sub>) as a clean oxidant

1-Bn-DHIQs to 1-Bz-DHIQs without concomitant excessive oxidation of 1-Bz-DHIQs to 1-Bz-IQs is very important for the syntheses of 1-Bz-DHIQ alkaloids and analogues. In this article, we developed a novel Cu(ii)-catalyzed and acid-promoted highly regioselective oxidation of tautomerizable C(sp3)-H bonds adjacent to the C-1 positions of various 1-Bn-DHIQs. It was observed that when 0.2 equiv. of Cu(OAc)2·2H2O

with permanent hearing loss in over 20% of patients requiring these life-sustaining antibiotics. There are currently no FDA-approved drugs that prevent hearing loss from aminoglycosides. A previous study by our group identified the plant alkaloid berbamine as a strong protectant of zebrafish lateral line hair cells from aminoglycoside damage. This effect is likely due to a block of the mechanotransduction
