Paper Title
Synthesis of Diimines From Cholestanone

Abstract
In this study, three new dimeric ketimine derivatives sterols were synthesized. First of all cholestanol was converted to cholestanone by using IBX. After than cholestanone was reacted with different amines respectively 1,2- ethylenediamine, 1,4-diaminobutane and 1,5-diaminonaphthalene in order to obtain ketimines. These compounds were characterized by 1 H, 13 C NMR. Keywords- Cholestanone, Dimeric sterols, ketimines
