An enantioselective synthesis of the natural antiproliferative agent quinocarcin was achieved by the directedcondensation of optically active α-aminoaldehyde intermediates. Condensation of the N-protected α-aminoaldehyde 1, prepared in eight steps (19% yield) from (R,R)-pseudoephedrine glycinamide, with the C-protected α-aminoaldehyde derivative 2, prepared in seven steps (34% yield) from (R,R)-pseudoephedrine
