title: Synthesis of 12-oxa, 12-aza and 12-thia cholanetriols.
abstract: An efficient synthesis of 12-hetero steroids was achieved via a Baeyer-Villiger oxidation and a photolysis as the key steps. We set out to describe in this paper the first synthesis of 12-aza steroids. The characteristic (1)H and (13)C NMR spectroscopic features of the synthesized compounds are reported.
