We have prepared a series of bis-bidentate complexes of rhenium that mimic the size, shape, and peripheral functionality of steroidal androgens. In a model system, we used 2D NMR and X-ray crystallographic analysis to show that adjacent N-methyl and oxo substitutents adopt an anti configuration during the coordination reaction. We have synthesized a bis-bidentate oxorhenium(V) complex whose structure and peripheral functionality mimic 5α-dihydrotestosterone. 2D-NMR analysis indicates that the N-methyl and oxo substituents are driven into the steroidal anti configuration (β-N-methyl, α-oxo) by the β-orientation of the methyl group equivalent to C-18. Thus, this metal complex provides a remarkable structural and stereochemical mimic of a steroid. Its in vivo stability, however, appears to be limited.
