A new series of 4,5-dihydroisoxazole-5-carboxylate derivatives were synthesized via [3 + 2] cycloaddition reaction between ethyl acrylate and nitrile oxide generated in situ in presence of Chloramine-T. The synthesized derivatives were characterized by Mass, IR and NMR Spectroscopy and their mesomorphic behavior were studied using DSC and Polarising Optical Microscopy.

Abstract : A novel reagent for the synthesis of isoxazolines has been reported. Aryl aldoximes were made to react with alkenes in the presence of KIO 3 as the oxidising agent. This new reagent has been useful as an oxidant in the synthesis of i

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.

Synthesis of a homologous series of mesogenic 4-(n-alkoxy)benzaldehyde oximes starting from 4-hydroxybenzaldehyde with n-alkyl bromide under phase transfer condition is described. Optical texture studies have been carried out using Leitz polarizing microscope and it is found that the synthesized compounds exhibit Smectic B, Smectic I and Smectic H phase.
