Abstract

An estradiol derivative, bearing an adenosine residue linked at C-16α by a three-carbon side chain, provides access to a new series of substrate-cofactor hybrid compound designed to potentially interact with two binding domains of the enzyme type 1 17β-hydroxysteroid dehydrogenase (17β-HSD). The synthesis of 5′-O-[3-(3′,17′β-dihydroxy-1′,3′,5′(10′)-estratrien-16′α-yl)propanoyl]adenosine (7) is reported focusing on the crucial last steps: the coupling of adenosine residue to estradiol side chain by an ester link and the appropriate final cleavage of three protecting groups.
