Synthesis of the enantiomer of 1α,25-dihydroxy vitamin D3 (calcitriol) and a diastereomer of 1α,25-dihydroxy vitamin D3 differing from natural product in configuration at all but one asymmetric carbon atoms

Convergent synthesis of ent-1α,25-dihydroxyvitamin D3 (ent-calcitriol, 2) and (1S,3S, 13S,14S,17S,20S) - 1α,25-dihydroxyvitamin D3 (5) using the ring A building blocks, 6 and 7, respectively, and rings CD building block 8, is describ

Synthesis and evaluation of A-ring diastereomers of 1α,25-dihydroxy-22-oxavitamin D3 (OCT)

A-ring diastereomers of 1α,25-dihydroxy-22-oxavitamin D3 (OCT) (2), 3-epi-1α,25-dihydroxy-22-oxavitamin D3 (3-epiOCT) (3) and 1,3-diepi-1α,25-dihydroxy-22-oxavitamin D3 (1,3-diepiOCT) (4) were synthesized by the convergent method. In vitro binding affinity for rat vitamin D binding protein and calf-thymus vitamin D receptor, differentiation-inducing activity on HL-60 cells, and transcriptional activity of 3-epiOCT (3) and 1,3-diepiOCT (4) were evaluated in comparison with OCT (2), 1-epi-1α,25-dihydroxy-22-oxavitamin D3 (1-epiOCT) (5) and 1α,25-dihydroxyvitamin D3 (1).
