Abstract

Rare earth-K-(S)-BINOL complexes were used to catalyze the nitroaldolreaction of the CD-ring 24-aldehyde precursors with 2-nitropropane ina good stereoselective manner. The obtained nitroaldol compound was easily converted into a synthetic intermediate 12 of 1 alpha,24(R)-dihydroxyvitamin D-3 1 by a denitration reaction using 2,2'-azobisisobutyronitrile (AIBN) and Bu3SnH.
