Several N-(trifluoroacetyl)-α-amino acid chlorides have been reacted with benzene, anisole, and veratrole in the presence of AlCl3 or SnCl4 to produce the corresponding aromatic ketones in fair to high yields.The products are reductible under neutral or acidic conditions to the corresponding N-(trifluoroacetyl)-β-hydroxy-β-arylakylamines or N-(trifluoroacetyl)-β-arylalkylamines.The latter can be readily detrifluoroacetylated by mild basic hydrolysis and thence converted to the corresponding 3-substituted 1,2,3,4-tetrahydroisoquinolines by condensation with formaldehyde.

Electrochemical reduction of tertiary nitroalkanes, 2-substituted-1,1-dimethyl-1-nitroethanes (1), was investigated in aqueous buffer solutions.In polarography, 1 with a phenyl group and/or a hydroxyl group at the 2-position showed an ill-defined wave in the weakly acidic and neutral pH region at relatively high negative potentials, in addition to a well-defined wave arising from the reduction of 1 to the corresponding hydroxylamine (2).Controlled potential electrolysis of 1 at the potential of the former wave gave the 1,1-dimethylethylamines (3) as well as the hydroxylamines 2.The amines 3 are formed exclusively from 2, probably via the O-protonated form.It is suggested that a phenyl group at the 2-position facilitates the reduction of 2 to 3 by enhancing the adsorption of 2 at the mercury cathode and that a hydroxyl group, while it interferes with the adsorption, assists the reduction by intramolecular hydrogen-bonding to stabilize the O-protonated form of 2.Keywords - tertiary nitroalkane; alkylhydroxylamine; electrochemical reduction; polarography; controlled potential electrolysis.
Improved Nitroaldol Reactions and Reductive Routes to Vicinal Aminoalcohols
Colvin, Ernest W.,Beck, Albert K.,Seebach, Dieter
, p. 2264 - 2271 (2007/10/02)
Regioselective and flexible procedures are described for the preparation of a variety of protected vicinal nitroalcohols 1, 3, and 5 (see Scheme 5), as is an efficient method for their reduction to the corresponding vicinal aminoalcohols 2, 4 and 6.
