Abstract

Maxacalcitol (1), a kind of active vitamin D drugs, was prepared from pregnenolone acetate (2) using a novel synthetic method including the combination of five-step organic transformations and one-step biological transformation. The new protocol was shorter, milder, and simpler than the reported approaches. The unoptimized overall yield was 0.178%. The structure of all intermediates and final product was confirmed by 1H NMR, 13C NMR and MS techniques.
