Abstract
The branched‐chain 2‐methylvaleric acid esters of cholesterol were prepared with (+), (−), and (±) configuration of the ester chain. Branching leads to monotropic smectic behavior in the pure esters; studies made by dissolving them in a compensated cholesteric or in a nematic solvent indicate that they have helical twisting powers which vary with the configuration at the asymmetric center.
