A new short route to chenodeoxycholic acid has been developed. The synthesis is based on the stereoselective introduction of the steroidal side chain via an ene reaction of methyl acrylate and a (17Z)-ethylidene steroid prepared from androstenedione.

A total synthesis of 1α,25S,26-trihydroxycholecalciferol (2) has been accomplished via an efficient convergent approach. The remote chiral center at C-25 was introduced by a regiospecific and diastereoselective 1,3-dipolar cycloaddition of the C-23
