1,8-Dioxo-decahydroacridines have been synthesized by the three-component reaction of aromatic aldehydes, aromatic amines (or ammonium acetate), and dimedone in the presence of sulfonic acid functionalized nanoporous silica (SBA-Pr-SO3H) under solvent-free conditions. Excellent yields, short reaction times, mild reaction conditions, an...

The historical exposures to aromatic amines of various occupational groups are briefly reviewed. Modern studies indicate that other occupational groups might have risks worth investigating; these include machinists and workers in the chemical industry. Details of a recent investigation into the exposure of dye workers are given which indicate a lowered risk in recent years since the introductio...

Aromatic amines are urinary bladder carcinogens in man and induce tumors at a number of sites in experimental animals including the liver, mammary gland, intestine, and bladder. In this review, the particular pathways involved in the metabolic activation of aromatic amines are considered as well as the specific DNA adducts formed in target and nontarget tissue. Particular emphasis is placed on ...

The aromatic amines 92-acetylaminofluorene (92-AAF) and two compounds structurally related to it (4-acetylaminobiphenyl [4-AAB] and 92-ace tylaminobiphenyl [92-AABJ) have induced cancer in the rat, 92-AAF and 4-AAB being particularly effective in this regard (15—17). Several aromatic amines (Table 4) have been reported to induce tumors in dogs, but of the three mentioned above only 92-AM? has...

The retinotoxic drug 1,5-di-(p-aminophenoxy)pentane inhibits the accumulation of all 11-cis-retinoids in the eye and can deplete preformed stores of them. It is shown here that these effects are not specific to 1,5-di-(p-aminophenoxy)pentane but are shared generally by primary aromatic amines containing a hydrophobic tail. Furthermore, certain clinically used drugs, such as the anti-inflammator...

Hydrogenation of nitriles to primary amines constitutes an atom-efficient and environmentally benign synthetic reaction. Herein we present a novel complex based on earth-abundant iron, and its application in the catalytic homogeneous hydrogenation of (hetero)aromatic, benzylic, and aliphatic nitriles to selectively form primary amines.

We describe an oxidative Strecker reaction that allows for direct cyanation of para-methoxyphenyl (PMP)-protected primary amines. A vanadium(V) complex was used as the catalyst and TBHP as the oxidant. The cyanation occurs at the α-C position bearing either an alkyl or an aromatic group. This method provides a direct access to α-aminonitrile from amines with one-carbon extension.
