Total synthesis of a CD-ring: Side-chain building block for preparing 17-epi-calcitriol derivatives from the Hajos-Parrish dione

An efficient synthesis of the key building block for 17-epi-calctriol from the Hajos-Parrish dione involving a sequence of diastereoselective transformation of the azulene core and the side-chain construction is presented.
