N-Acyliminoiodinanes were characterized for the first time by X-ray structural analysis. The ortho-methoxymethyl group and the carbonyl oxygen coordinate to the iodine atom of the iminoiodinane. Activation of the N-acyliminoiodinane was achieved by photoirradiation at 370 nm, thereby enabling reaction with various silyl enol ethers to give α-aminoketone derivatives in good to high yield. N-sulfonyliminoiodinanes bearing ortho substituents were used in photoinduced amination.

A series of 5-phenyl-substituted-N-alkyl-imidazolin-2-ones with potent radical-scavenging activity and lipid peroxidation inhibitory activity was synthesized. Many of the compounds showed memory-improving effect in animal models independent of the inhibitory activity on lipid peroxidation.

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.
Friedel-Crafts Acylation with N-(Trifluoroacetyl)-α-amino Acid Chlorides. Application to the Preparation of β-Arylalkylamines and 3-Substituted 1,2,3,4-Tetrahydroisoquinolines

Several N-(trifluoroacetyl)-α-amino acid chlorides have been reacted with benzene, anisole, and veratrole in the presence of AlCl3 or SnCl4 to produce the corresponding aromatic ketones in fair to high yields.The products are reductible under neutral or acidic conditions to the corresponding N-(trifluoroacetyl)-β-hydroxy-β-arylakylamines or N-(trifluoroacetyl)-β-arylalkylamines.The latter can be readily detrifluoroacetylated by mild basic hydrolysis and thence converted to the corresponding 3-substituted 1,2,3,4-tetrahydroisoquinolines by condensation with formaldehyde.
