Naphthalene-catalysed lithiation of phenone imines in the presence of carbonyl compounds: preparation of 1,2-aminoalcohols
摘要:
The lithiation of different phenone imines 1 with an excess of lithium powder and a catalytic amount (8 mol %) of naphthalene in the presence of several carbonyl compounds 2 in tetrahydrofuran at temperatures ranging between -78 and 20-degrees-C leads, after hydrolysis with water, to the corresponding 1,2-aminoalcohols 3 in moderate yields.

Samariumdiiodide in the presence of a catalytic amount of nickel diiodidemediates a very fast dimerization of imines into vicinal diamines and the mixed coupling of imines and ketones to give β-amino alcohols.
