摘要：

In the presence of catalytic amounts of optically active aminoalcohols, the irradiation of alpha-disubstituted indanones, tetralones and propiophenones bearing at least one hydrogen in the gamma-position led to Norrish type II cleavage compounds which were obtained with enantiomeric excesses reaching 89 %. The influence of the reaction conditions (temperature, wavelength of the W light and nature of the aminoalcohol) has been analyzed.
