Stereoselective Synthesis of Cyclopentanones by Reductive Cleavage of 6-Oxonorbornane-2-carboxylates and Its Application to the Synthesis of 1α,25-Dihydroxyvitamin D3 CD Ring

A novel chiral synthesis of the CD-ring 2 of 1α,25-dihydroxyvitamin D3 (1a) is described.The optically active D-ring keto ester 3c was prepared by reductive cleavage of 6-oxonorbornane-2-carboxylate 4c with lithium naphthalenide. 1,2-Transposit
