A new synthetic method of imidoyliodides has been devised which involves the Beckmann rearrangement of oxime derivatives with trimethylsilyl iodide or diethylaluminum iodide. This allows a one-pot procedure for a α-arylation of amines in synthetically useful yields.

The reaction of aromatic Claisen rearrangement of N-(1-methylbut-2-en-1-yl)anilines in the presence of p-toluenesulfonic acid was investigated. N-Tosyl-2-(1-iodoethyl)-3-methylindoline derivatives were obtained; one of them exhibited a cytotoxic activity.

The synthetic and kinetic regularities of the amino-Claisenrearrangement (ACR) were studied for the transformation of 2,5-dimethyl-N-(pent-3-en-2-yl)aniline. The ACR products are formed due to the conversion of a binary π-complex formed by the reaction of N-alkenylaniline hydrochloride with hydrochloride of the solvent (2,5-dimethylaniline).

One-pot reduction of enaminones to syn gamma-aminoalcohols can be efficiently performed by lithium borohydride in the presence of cerium chloride as Lewis acid. Selectivities are very good with respect to classical reduction method of these products. (C) 2002 Elsevier Science Ltd. All rights reserved.
