    • Compound 9 and the related benzophenone 3 proved to be photolabile in solution, although they could be stored for prolonged periods when kept as solids in the dark. Photoreactivity of 2-(alkoxymethyl)benzophenones is well known; for example, see: (a) Oka, M.; Konishi, M.; Old, T. Tetrahedron Lett. 1990, 31, 7473-7474. (b) Kraus, G. A.; Wu, Y. J. Org.

    • This figure represents a lower limit on the selectivity, since our limits on determining the enantiomeric purity of 26b leave open the possibility that (+)-1 is contaminated by as much as 2% of the potent inhibitor (-)-1.

    • note
    • Although product often formed without 2-propanol addition, progress of the reaction was highly variable from run to run and possibly depended on adventitious introduction of moisture. We believe the 2-propanol served to partially desilylate the initially formed and unreactive persilylated compound.
