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 H-1 NMR, C-13 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 (S-A) and chiral smectic phases (S-c*), some at and just above room temperature.
