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-d
在我们对维生素D的持续研究中,我们专注于维生素D 3侧链24位,这是人CYP24A1的主要代谢位点。为了抑制维生素D 3的代谢,24,24-二氟维生素D 3类似物是重要的候选物。在本文中,我们报告了将二氟单元引入24位的实际方法,以合成24,24-二氟CD环(1)和24,24-二氟25-羟基维生素D 3(2)。
