Twenty-nine arylisopropylamines, substituted at the β-position of their side chain by an oxo, hydroxy, or methoxy group, were evaluated in vitro as MAO-A and MAO-B inhibitors. The oxo derivatives ('cathinones') were in general less active as MAO-A inhibitors than the corresponding arylisopropylamines, but exhibited an interesting MAO-B inhibiting activity, which was absent in the hydroxy, methoxy, and β-unsubstituted analogues. These results suggest that selective affinity for the two MAO isoforms in this family of compounds is modulated not only by the aryl substitution pattern but also by the side-chain substituents on the arylalkylamine scaffold.

Treatment of a nitroalkene with nucleophiles, followed by silylation of the resulting nitroalkane and subsequent treatment with m-chloroperbenzoic acid provides α-functionalized carbonyl compounds in good yields.

Cyclisation of a series of 2-substituted 2-acylamino-1-arylalkan-1-ols using phosphorus pentaoxide in refluxing decalin is shown to lead to rearranged, i.e. 4-substituted, isoquinolines in addition to the anticipated 3-substituted isomers.The products arise largely via 5-phenyl-Δ2-oxazoline intermediates and the formation of the rearranged isoquionolines from these intermediates is fully discussed.The pathway is not substantially altered when 2-benzamido-1-methoxy-1-phenylalkanes are cyclised.
