An efficient, two-stage, continuous-flow synthesis of 1α,25-(OH) 2-vitamin D3 (activated vitamin D3) and its analogues was achieved. The developed method afforded the desired products in satisfactory yields using a high-intensity and economical light source, i.e., a high-pressure mercury lamp. In addition, our method required neither intermediate purification nor high-dilution conditions. The Royal Society of Chemistry 2012.

The invention provides novel 1α-hydroxy vitamin D compounds and a method for their preparation from 1α-hydroxy-25-hydrogen cholesta-5,7-dienes by irradiation and isomerization techniques. The invention also includes the said 1α-hydroxy-25-hydrogen-cholesta-5,7-dienes and the corresponding cholest-5-enes. The new compounds may be obtained in a crystalline form substantially free from isomeric or other impurities arising from manufacture.
