The intensities of a multiplet at 4.55 ppm (1 H) in the spectrum of 1-phenylpropanol, a singlet at 9.98 ppm (1 H) in the spectrum of benzaldehyde, and a singlet at 4.64 ppm (2 H) in the spectrum of benzyl alcohol were compared with the intensity of a doublet at 8.4 ppm (2 H) in the spectrum of 3. The other reactions were analyzed similarly.

    • BINOL at room temperature with diethylzinc and benzaldehyde in toluene was reported in ref 8a to give no appreciable reaction and in ref 8b to transform 37% of the benzaldehyde and give 1-phenylpropanol with an ee of 32.9%. To provide a uniform comparison, the reaction parameters that had been optimized for [5]HELOL were applied to both it and to BINOL.

    • note
    • 1H NMR analysis similar to that carried out for (P,P)-11 was impossible because no cleanly resolvable peaks could be found in the spectra of (P,P)- and meso-3. Their resonances were too broad. CD spectroscopy proved too imprecise to measure small changes when less than 10-20% stereomutation had taken place.
