The first synthesis of analogues of the natural hormone 1alpha,25-dihydroxyvitamin D(3) (1a) with substituents at C-12 is reported. The following are the relative affinities of the novel compounds for the vitamin D receptor (VDR) compared to that of 1a (100%): 1alpha,12alpha,25-(OH)(3)-D(3) (1b, 1%), 1alpha,25-(OH)(2)-12-methylene-D(3) (1c, 50%), and 1alpha,25-(OH)(2)-12beta-methyl-D(3) (1d, 440%).
