    • While several workers have introduced chirality into the interior of dendritic structures, only those structures reported by Mitchell and Chapman possess moieties (amide linkages) capable of providing strong enthalpic contributions to guest binding. See references 9 and 17.

    • note
    • Transesterification between the phosphonate ester and the substrate was observed to occur during this reaction resulting in a small amount of 13 existing as the ethyl, rather than methyl, ester (see Experimental Section). This was avoided in the preparation of 14 by employing ethyl ester 12, rather than methyl ester 11.

    • The optical purities of both 3 and 4 were essentially the same as that of diols 21 and 22 (>99% ee by chiral HPLC).
