Stereoselective synthesis of C24-hydroxylated vitamin D3 analogs: A practical and expeditius route to calcipotriol

The synthesis of the clinically important drug calcipotriol (2, MC903) is described as an example of a new and efficient approach to C24-hydroxylated analogs and metabolites of vitamin D3 (1). The key step of the process is the generation of the C24 stereocenter by DAIB [(-)-3-exo-(dimethylamino)isoborneol]-catalyzed addition of the alkenylzinc derivative of alkyne 3 to cyclopropylcarboxaldehyde.
