During our ongoing studies of vitamin D, we focused on the vitamin D3 side-chain 24-position, which is the major metabolic site of human CYP24A1. In order to inhibit the metabolism of vitamin D3, 24,24-difluorovitamin D3analogues are important candidates. In this paper, we report the practical introduction of the difluoro-unit to the 24-position to synthesize 24,24-difluoro-CD ring (1) and 24,24-difluoro-25-hydroxyvitamin D3 (2).

Twelve new analogs of 19-nor-1α,25-dihydroxyvitamin D3 6-17, were prepared by a multi-step procedure from known alcohols 18 and 19. We have examined the influence of removing two methyl groups located at C-25, as well as the 25-hydroxy group, o
