    • Control experiments conducted without nitroalkene revealed the complete absence of self-aldol reaction. Concurrent with this research, a related design which works for the anti-Mannich reaction has been reported: S. Mitsumori, H. Zhang, P. H.-Y. Cheong, K. N. Houk, F. Tanaka, C. F. Barbas III, J. Am.

    • This catalytic system seems to be less effective for ketones; for instance, using catalyst 18 (10 mol%) and cyclohexanone (3 equiv) at room temperature gave d.r. 83:17 and 20% ee; using tetrahydrothiopyran-4-one (10 equiv) at 0°C gave d.r. > 99:1 and 60% ee.
