(Chemical Equation Presented) A highly efficient, three-component one-pot benzylation and allylation of aromatic and aliphatic aldehydes and amines affords the corresponding homobenzylamines and homoallylamines in good to excellent yield. The procedure is

A silver-triflate catalyzed cascade of in situ-oxidation and allylation of arylbenzylamines is reported. The 2,2,6,6-tetramethylpiperidine-1-oxoammonium tetrafluoroborate is employed as a mild oxidant which is compatible with both catalyst and ligand. Racemic BINAP is also utilized to assist with the catalyst in regulating the yields of products. Various homoallylic amines are obtained in 39–99% yields.
A simple and efficient method for the three-component synthesis of homoallylic amines catalyzed by indium triflate

experimental part, p. 1609 - 1612 (2010/07/02)
Indium triflate catalyzes efficiently the one-pot three-component condensation of aldehydes, amines, and allyltributylstannane to afford the corresponding products of homoallylic amines in excellent yields at room temperature. All reactions were carried o

(Chemical Equation Presented) Aldimines derived from aryl and non-enolizable aliphatic aldehydes were allylated with allyl bromide mediated by indium powder in [bpy][BF4] (bpy = N-butylpyridine) to give good yields of the corresponding homoallylic amines. Selective formation of monoallylated amines can be achieved by varying the amount of bromide ion additive in the form of [bpy][Br]. The transient organoindium intermediates, allylindium-(I) and allylindium(III) dibromide formed in the reaction, were studied by NMR spectroscopy to explain the selectivity.
SYNTHESIS OF 2-ALKYL(ARYL, HETARYL)-4-METHYL-1,2,3,4-TETRAHYDROQUINOLINES

We have developed a preparative, three stage of synthesis of substituted 1,2,3,4-tetrahydroquinolines.Treatment of N-aryl-imines with allylmagnesium bromide gave N-aryl-N-alkenylamines which were cyclized to the tetrahydroquinolines.The configurations and
One-step Synthesis of Cyclic Compounds by Electrochemical Reduction of Unsaturated Compounds in the Presence of Dielectrophiles

The one-step synthesis of cyclic compounds is achieved in a few cases by electroreduction of unsaturated compounds in DMF, at a mercury pool cathode, in the presence of a more difficulty reducible dielectrophile.Unsaturated compounds include activated olefins, aromatic Schiff bases, ketones, and azo, nitroso, and nitro compounds.Four dielectrophiles are used; they are tri- or tetramethylene bromide, succinyl chloride, and 4-bromobutyryl chloride.The electrochemical synthesis of derivatives of cyclohexane, piperidine, pyrrolidine, hexahydropyridazine, tetrahydropyridazinone, tetrahydropyridazinedione, tetrahydrooxazine, isoxazolidine, and spirolactone can be succesfully performed.Their yields range from 8 to 78percent depending on competitive reactions.Results of chemical reduction by alkali metals and electrochemical reduction are compared.
