we describe a synthetic strategy to access 1α,25-dihydroxyvitaminD3 (calcitriol) analogs with natural or unnatural configuration at C20 and unsaturation at the D-ring. The synthetic approach is exemplified by the synthesis of two potent analogs, namely 1α,25-dihydroxy-16-en-23-yne-vitamin D3 and 1α,25-dihydroxy-20-epi-24a-homo-26,27-dimethyl-vitamin D3. A key feature of the synthetic strategy is
