A simple homologous series of 3-[4-alkyloxyphenyl]-5-[3,4- methylenedioxybenzyl]-2-isoxazolines having chiral sources have been synthesized by the reaction of nitrile oxides isolated from the dehydrogenation of 4-alkyloxyphenyl aldoximes using chloramine-T with safrole. Synthesized compounds structures have been confirmed by 1H NMR, 13C NMR, mass spectral analysis and optical texture studies have been carried out using Leitz polarizing microscope. The synthesized compounds exhibit cholesteric phase or chiral nematic phase (N*), smectic A (SA) and chiral smectic phases (SC*), some at and just above room temperature.
