一般描述
Methyl 3-chloro-3-oxopropionate reacts with 4-cyano-1,1′-biphenyl derivatives bearing ω-hydroxyalkyl substituents to yield liquid-crystalline linear malonates and cyanoacetates.
应用
Methyl 3-chloro-3-oxopropionate was used as a reagent in the synthesis of resin-bound 4-tosyl quinolinone, 1-anthracen-9-ylmethyl 3-methyl 2,2-dimethylmalonate and 1-(4-(3,5-dihydropyren-1-yl)butyl)-3-methyl 2,2-dimethylmalonate.

4-Cyano-1,1'-biphenyl derivatives bearing ω-hydroxyalkyl substituents were reacted with methyl 3-chloro-3-oxopropionate or cyanoacetic acid, giving liquid-crystalline linear malonates and cyanoacetates. These compounds formed monotropic nematic phases at 62 °C down to ambient temperature upon cooling from the isotropic liquid. The mesomorphic
