The synthesis of the cholestano-fused tetrathiafulvalene (TTF) 3 and cyanoethyl-protected cholestano TTF 4 is described. Compound 4 was deprotected under basic conditions and then treated with 2-bromoethanol or 1,2-dibromoethane to give the corresponding cholestano (hydroxyethyl)thio TTF 18 and the cholestano ethylenedithio TTF 19, respectively. The synthesis of the electron accepters, cholestanonaphthoquinone 20 and the corresponding dicyanonaphthoquinodiimine 5 is likewise reported.
