Our previous studies revealed that recombinant human CYP3A4 converted 2α-(3-hydroxypropoxy)-1α,25-dihydroxyvitamin D<sub>3</sub> (O2C3), which was a more potent binder to vitamin D receptor (VDR) than the natural hormone, 1α,25-dihydroxyvitamin D<sub>3</sub> (1α,25(OH)<sub>2</sub>D<sub>3</sub>, <b>1</b>), to 1α,2α,25-trihydroxyvitamin D<sub>3</sub> (<b>2</b>). Here, we synthesized <b>2</b> using the Trost Pd-mediated coupling reaction between an A-ring precursor and a CD-ring bromoolefin and evaluated its preliminary biological activity. We found that metabolite <b>2</b> from O2C3 was still active as a VDR ligand while maintaining human VDR binding affinity (27.3% of 1α,25(OH)<sub>2</sub>D<sub>3</sub>) and HL-60 cell differentiation activity (62% of 1α,25(OH)<sub>2</sub>D<sub>3</sub>).
