    • Acid-mediated ester hydrolysis was chosen because our previous experience with the analogous pyrrolidine acid series (e.g. 2) had shown that base-mediated hydrolysis can result in epimerization at the carbon α to the carboxylic acid (e.g. analogs 22-25 in Scheme 3).

    • 1H COSY and HMQC. All proton and carbon assignments were also confirmed using HMBC. For example, in the HMBC spectrum, H-24 (δ 6.73) showed a correlation with C-29 (carbonyl, δ 153.2), while the benzylic protons H-22 (δ 3.36, doublet) showed connectivity with C-23 (δ 115.3), C-24 (δ 123.7), C-28 (δ 40.7), C-16 (δ 116.0), C-17 (δ 141.5), and C-18 (δ 121.9, as shown in Fig. 4). Complete analysis from this set of NMR experiments showed that the structure was unequivocally 33a rather than 34a.

    • note
    • 50 values (μM) for PPARα or γ agonist activity were calculated as the concentration of the test ligand (μM) required for the half-maximal fold induction of HEK293 cells. The 'intrinsic activity' of a test ligand is defined as its activity at 1 μM (expressed as a percentage) relative to the activity of the primary standards at 1 μM. Also see Ref. 9a.
