continuation of our efforts directed to vitaminD compounds of promising biological properties, 19-norvitamins 9–13, possessing a 3′-hydroxypropylidene fragment attached to C-2 and shortened 17β-alkyl chains, were synthesized. A new synthetic pathway providing the CD-ring ketones 20–24 is described starting from the epimeric aldehydes 25 and 26. The hydrindanones 20–24 were subjected to the Wittig–Horner

Disclosed are 1α-hydroxy-2-(3′-hydroxypropylidene)-19-nor-vitamin D compounds, pharmaceutical compositions, and methods of making and treatment thereof. The compounds are generally directed to biologically active 2-alkylidene-19-nor-vitamin D compounds and analogs thereof characterized by the presence of a 3′-hydroxypropylidene moiety at C-2 and the presence of an abbreviated alkyl side-chain free of any hydroxyl moiety.
