    • 5 was assigned on the basis of an X-ray crystal structure of the p-methoxy derivative carried out at UBC (Olovsson, G.; Trotter, J., unpublished results). The absolute configuration of the photoproducts has not been assigned. The possibility that what we took to be the minor enantiomer of photoproduct 2d on HPLC was an unidentified impurity was ruled out by (1) showing that this peak had exactly the same retention time as in the case of the racemic mixture, (2) checking the UV absorption spectrum of each peak (diode array detector), and (3) checking the enantiomeric excesses on two different HPLC columns (Chiralcel OD and OJ). Attempted determination of the enantiomeric excesses by chiral shift reagent NMR techniques was unsuccessful.

    • Photolyses were also carried out on samples in which the order of inclusion was reversed, i.e., inclusion of ketone followed by inclusion of chiral inductor, as well as on samples prepared by simultaneous adsorption of ketone and chiral inductor from hexane solution. In both instances, the enantiomeric excesses obtained were considerably lower than those reported in Table 1.
