Blue phases (BPs) have received considerable attention as light shutters in the next generation of liquid crystal (LC) displays. However, no simple and efficient chiral dopant for induction of BPs of commercially available rodlike LC compounds has been reported. In this study, both (R) and (S) forms of novel chiral dopants were synthesized, showed extremely high helical twisting power values in nematic LC compounds, and induced stable BPs with a small amount of our chiral dopants (3-5 mol %). In enantiomeric excess controlled experiments, we found novel phenomena in their physical properties, such as generation of a metastable chiral nematic phase between an isotropic state and a BP.

A multicomponent synthesis of 3,4-disubstituted N-aminopyrrolidine-2,5-diones is described. A mixture of N-isocyaniminotriphenylphosphorane, an aldimine and Meldrum's acid undergoes an addition reaction under mild conditions in aqueous THF to produce 1-amino-4-aryl-2,5-dioxo-N 3 -aryl-3-pyrrolidinecarboxamides diastereoselectively in good to excellent yields. 1 H NMR analysis showed that the two substituents on C-3 and C-4 positions of the obtained pyrrolidine-2,5-diones are trans.
