Synthesis and mesomorphic behaviour of 5α-cholest-8(14)-en-3β-yl alkanoates
Abstract
A homologous series of 5α-cholest-8(14)-en-3β-yl alkanoates has been synthesized via transacylation of 5α-cholest-8(14)-en-3β-ol with the imidazolides of alkanoic acids. All alkanoates of this series exhibit mesomorphic behaviour in the pure state except the formate and acetate. The mesomorphic transition temperatures are considerably lower than those of the corresponding cholesteryl derivatives.
