APPLICATION OF WITTIG AND CLAISEN REARRANGEMENTS IN STEROID SIDE CHAIN SYNTHESIS. A HIGHLY STEREOCONTROLLED ENTRY TO EITHER (22S)- OR (22R)-HYDROXY-23-CARBOXYLIC ACID

An efficient approach to either (22S)- or (22R)-hydroxy-23-carboxylic acid side chain is described which relies on the stereochemical transmission via Wittig or Claisen sigmatropic rearrangement, respectively.
