    • Triazoles fused across C6-C7 were inactive. Additionally, C7-C8 imidazoles appear much less promising than the C7-C8 triazoles we now report. D. Parker, R. Wilkening, unpublished results.

    • Most often a Chiralcel OJ column was employed using a mixture of EtOH and heptane as the eluent. Compounds (-)-40 and (-)-47 were prepared from (-)-38 (via reprotection and further elaboration).

    • 2-substituent, often providing no selectivity or increased selectivity for the undesired regioisomer. Unfortunately in several cases the nitration selectivity opposed the bromination selectivity. Future utility of a halo-protection strategy will require a starting material with a pre-installed bromine.

    • 50 values that are reproducible to within a factor of 2-3. Most compounds are single point determinations. For estradiol, the binding data reflect an average of over 100 determinations at 3 h of incubation.

    • A crystal structure of compound 1 co-crystallized with ERβ supported the configurational assignment of the active enantiomer as S. (see Ref. 17). By analogy we have assigned the more active enantiomer of the triazolo-tetrahydrofluorenones described herein to also be S. The active enantiomer was found to have a negative rotation in each case determined.

    • note
    • The difference between the PK of the individual enantiomers of 29 was much more dramatic than we expected based on results for a closely related pyrazole analog (Ref. 19). While many other racemic analogs were examined for rat pharmacokinetics, given the significant difference in the PK profiles for the individual enantiomers, we have not included data for these analogs.
