Rezumat:

Steryl carbamates were prepared by direct reaction of sterols with alpha, alpha, alpha-trifluoro-m-tolyl isocyanate to evaluate the effect of the meta-CF3-phenyl group attached at the C-3 position of the sterol nucleus. The thermodynamic properties of steryl-carbamates were characterized by DSC and the texture of the mesophases was determined with a Boetius hot stage.
