title: Novel A-ring analogs of the hormone 1alpha,25-dihydroxyvitamin D3: synthesis and preliminary biological evaluation.
abstract: Prepared from a commercial prostaglandin building block, novel vitamin D3 analogs with a contracted five-membered A-ring were designed and synthesized to mimic the A-ring diol structure of the natural hormone 1alpha,25-dihydroxyvitamin D3. Prepared from commercial 1,4-cyclohexanedione, a structurally simplified analog was designed and synthesized in which a suitably oriented primary allylic hydroxyl group at the C-2 position might be a surrogate for the biologically important 1alpha-OH in the natural hormone.
