Selective reductive coupling of nitro aliphatic compounds with aldehydes in hydrogen using gold catalyst
Nitrones were synthesized in good yields directly from nitro aliphatic compounds, aldehydes, and H2 using highly dispersed gold nanoparticles on titania. The high selectivity for nitrone synthesis contrasts with the platinum supported on carbon

The use of bis(aminol) ethers derived from aliphatic primary amines in the synthesis of secondary and tertiary amines
A series of bis(aminol) ethers were prepared from primary aliphatic amines and benzylamine together with formaldehyde and either ethanol or methanol; they were reacted with electrophiles to give N-alkyl-N-alkoxymethyl-methyleneiminium salts which gave mixtures of secondary and tertiary amines in reactions with electron rich aromatic compounds: sequential reactions with two different nucleophiles gave the expected tertiary amines.

aminoalkylbenzotriazoles: Reagents for the aminoalkylation of electron rich heterocycles
Secondary and tertiary aminoalkylbenzotriazoles react with pyrrole, indole, their N-methyl analogs and with 2-methylfuran under mild reaction conditions in the presence of a Lewis acid to afford selectively the corresponding secondary or tertiary amines.

A new route to secondary amines from bis-(alkoxymethyl)-alkylamines - The activation of an aminomethyl group and protection of the product by the same functional group
Treatment of N,N-bis(alkoxymethyl)alkylamines with a variety of acidic reagents affords good yields of N-alkoxymethyl-N-alkylmethyleneiminium salts which react with trimethylsilyl enol ethers, and nucleophilic aromatic substrates to form protected secondary amines or tertiary amines by domino reactions; silyl ketene acetals afford tertiary amines only.
