The syntheses of 13α-substituted-des-C-ring-19-nor-1α,25-dihydroxyvitamin D3 analogs (12a, 12b) are described. The sequence involves using vitamin D3 as a starting material, cleavage of the six-member ring by Baeyer Villiger reaction, introducing the C-25-hydroxy group by ruthenium oxide, and coupling the D-ring and A-ring by Horner-Witting reaction.

Key words: 13α-substituted, des-C-ring-19-nor-vitamin D3, analogs, synthesis
