4β,5-Epoxy-5β-cholestan-3-one (I) reacts with thiourea to afford 5β-hydroxycholest-3-eno-2'-aminothiazole (II) while with thiacetamide it furnishes 3,5-cholestadieno-2'-methylthiazole (III) and 5β-hydroxycholest-3-eno-2'-methylthiazole (IV). 6β-Chloro-5-hydroxy-5α-cholestane (V) on treatment with KSCN in dimethylformamide gives cholesta-4,6-diene (VI), 5α-chloestan-6-one (VII), 5-hydroxy-5α-cholestan-6α-yl isothiocyanate (VIII), 5-hydroxy-5α-cholestan-6-one (IX) and 5α-cholestano-2'-thiooxooxazolidine (X).The structures of these compounds have been established on the basis of spectral properties, analytical data and also by direct comparison with authentic samples where available.
