Abstract
An efficient method for the synthesis of aryl aminocholestanes, using a chlorotriisopropoxytitanium(IV)-mediated reductive amination reaction of 5α-cholestane-3,7-dione, is reported. A series of 3,7-diarylaminocholestane derivatives were prepared according to this methodology in up to 98% yield. These compounds were primarily characterized by (1)H NMR, (13)C NMR, and mass spectrometry.
