(SP,SC)-5-Ethyl-3-(2-methylbutoxy)-7-(4-undec-10- enoxyphenoxycarbonyl)-5H-dibenzophosphole 5-oxide, the first example in the literature of a new asymmetrically substituted dibenzophosphole-based group of systems with liquid-crystal properties is described.

A synthesis of a new family of chiral dibenzophosphole 5-oxides is described. Using high-yield known reactions we report a method for the synthesis and optical resolution of chiral dibenzophospholes from an unsubstituted system. These molecules are the first examples of a new asymmetrically substituted dibenzophosphole-based group of systems with liquid crystal properties.
Enantiomeric resolution and determination of the absolute configuration of dibenzophosphole 5-oxides

, p. 1987 - 1997 (2007/10/03)
The resolution of asymmetrically substituted dibenzophospholes via chromatographic separation of their cyclopalladium derivatives is described for the first time. The absolute configuration of the phosphorus atom was determined by X-ray crystallographic a
