    • note
    • The absolute stereochemistry of the adducts is presumed to parallel that previously reported for the tert-butyl-substituted allenes, for which X-ray crystallographic analysis of a derivative was possible (ref 2a). To date, we have been unable to obtain crystalline material of 21-28 and their derivatives.
