An expedited approach to the vitamin D trans-hydrindane building block from the Hajos dione

Efficient and operationally simple synthesis of the key trans-hydrindane alcohol building block for the synthesis of calicitriol (1α,25- dihydroxyvitamin D3) has been developed. Epoxy alcohol prepared almost quantitatively from the Hajos dione
