Synthetic studies of vitamin D analogues. XI. Synthesis and differentiation-inducing activity of 1α-25-dihydroxy-22-oxavitamin D3 analogues

Six analogues of 1α,25-dihydroxy-22-oxavitamin D3 (OCT) (2), 26,27-dimethyl OCT (5), 26,27-diethyl OCT (6), 24-norOCT (7), 24-homoOCT (8), 24-dihomoOCT (9), and 24-trihomoOCT (10) were synthesized from the 20(S)-alcohol (11) as the common start
