Abstract

Access to the calcitriol analogues with a tetrazole ring at the side chain was very efficiently achieved using the Calverley-Choudhry approach instead of the Wittig-Horner method, which gave very low yields.

Key words

1α,25-dihydroxyvitamin D₃ - tetrazole - heterocycles - azasteroids - Windhaus-Grundmann ketone
