SYNTHESIS OF ACTIVE FORMS OF VITAMIN-D .2. SYNTHESIS OF ANALOGS AND THEIR BIOLOGICAL-ACTIVITIES

The recent developments in the synthesis of Vitamin D metabolites have been described in Part I of this series. This review covers the recent advances in the synthesis of analogs of the metabolites including modifications in steroidal ring A and side chain. Biological activites of those analogs and structure-activity relationships are also discussed. © 1979, The Society of Synthetic Organic Chemistry, Japan. All rights reserved.
