A powerful approach to synthesize a-trifluoromethylated amines has been developed. The method is operationally simple, broad in substrate scope and amenable to scale-up using trifluoroacetic anhydride. Meanwhile, the strategy not only provided a versatile approach to synthesize a-trifluoromethylated amines but also provides a new method for exploring the new reactivity of trifluoroacetic anhydride.

compared to previously studied THIQ-type inhibitors, except for 16 which was found to have good affinity for PNMT (PNMT K(i) = 0.52 microM). Compounds 14 and 16 proved to be the most selectiveinhibitors in this small series of compounds and are some of the most selectiveinhibitors of PNMT known (14, selectivity alpha(2) K(i)/PNMT K(i) = 700; 16, selectivity alpha(2) K(i)/PNMT K(i) > 1900).

Reaction of allylmagnesiumbromide with trifluoromethyl oximes is different than with other Grignard reagents. On the other hand, allylmagnesiumbromide acted as a reducing agent towards trifluoromethyl ketones. By using an excess of this Grignard reagent, an exclusive addition reaction is obtained. A single electron reaction is suggested to explain the reductive process.

Tetrahydro-3-benzazepines and tetrahydroiso-quinolines are synthesized in one,step from allenes and phenylethylamines or benzylamines,Mechanitically, it is assumed that activation of an aromatic ring with Pd(II) occurs, directed by the primary amine, leading to the formation of a palladacycltinto which'ari, allene then undergoes insertion. The resulting, pi-allyl intermediate cyclizes to the products by aniptramolecular allylic alkylation. The process is particularly useful with 2,3-butadienoates and amines having a quaternary carbon at the alpha-position.
