A total synthetic strategy of 20S-hydroxyVitamin D3 [20S-(OH)D3] involving modified synthesis of key intermediates 7 and 12, Grignard reaction to stereoselectively generate 20S-OH and Wittig-Horner coupling to establish D3 framework, was completed in 16 steps with an overall yield of 0.4%. The synthetic 20S-(OH)D3 activated Vitamin D receptor (VDR) and initiated the expression of downstream genes. In addition, 20S-(OH)D3 showed similar inhibitory potency as calcitriol [1,25(OH)2D3] on proliferation of melanoma cells.
