Definitions

  • the present invention relates to novel biologically active vitamin D 3 analogues which include an alcohol or fluoride substituent in the 2-position and methods for their preparation.
  • Vitamin D 3 analogues have been recognized as having important biological activities. It is known, for example, that vitamin D 3 analogues can be used to control calcium and phosphate
  • vitamin D 3 produces 1 ⁇ ,25-dihydroxyvitamin D 3 (calcitriol) during normal metabolism.
  • Calcitriol is a potent regulator of cell differentiation
  • Calcitriol is also known to affect the immune system and this compound, as well as a variety of synthetic vitamin D 3 derivatives have been used in practical, clinical chemotherapy of such diverse human illnesses as osteoporosis, cancer, immunodeficiency syndromes and skin disorders such as dermatitis and psoriasis.
  • Calcitriol may be structurally represented as follows:
  • the upper and lower ring portions of calcitriol may be called, for ease of reference, the C/D-ring and A-ring, respectively. DESCRIPTION OF THE RELATED ART

  • bone e.g., hip
  • osteoporosis ranks third to heart disease and cancer in terms of prevalence. It is estimated that 30% of women at 75 years and 40% of women at 85 years have abnormal bone loss. Calcitriol is being used, especially in Japan where dietary intake of calcium is low, for treatment of osteoporosis .

  • dienophile 4Z led exclusively to cis-4, 5-oriented products 6a and 6b. Therefore, these polarized 2+4- cycloadditions must occur in a concerted rather than in a step-wise fashion.
  • the assignments of the 4,5-positional relationships were based on extensive precedent 5, and the assignments of the 4,5-stereochemical relationships were based on the match of the 400 MHz 1 H NMR J 4,5 coupling constants with those calculated using the Karplus eguation for energy-minimized structures generated using
  • Bicyclic lactone 6a the very major cycloadduct, differed in a characteristic way from bicyclic lactone 6b in terms of the chemical shift of the bridgehead hydrogen atom ( ⁇ 4.98 vs. 5.04) and the chemical shift of the C 4 hydrogen atom ( ⁇ 4.55 vs. 3.83). Also,

This stereochemical outcome was expected based on the results in Scheme I with the 3-sulfonyl-2-pyrone and was confirmed by the observed large 1 H NMR J 4.5 coupling constant (8.6 Hz) and by the
