Synthetic studies of vitamin D analogues. IX. Synthesis and differentiation-inducing activity of 1α,25-dihydroxy-23-oxa-, thia-, and azavitamin D3

Three vitamin D3 analogues, 1α,25-dihydroxy-23-oxavitamin D3 (3), 1α,25-dihydroxy-23-thiavitamin D3 (4) and 1α,25-dihydroxy-23-azavitamin D3 (5) were synthesized. In the differentiation-inducing activity of huma
