Synthesis and Antioxidant Activity of Styrylsulfonylmethyl 1,3,4-Oxadiazoles, Pyrazolyl/Isoxazolyl-1,3,4-oxadiazoles

Chemical and Pharmaceutical Bulletin, 2013
A new class of mono and bis heterocycles-styrylsulfonylmethyl 1,3,4-oxadiazoles, pyrazolyl/isoxazolyl-1,3,4-oxadiazoles were prepared and studied their antioxidant activity. The compound methyl substituted 2-(p-methylphenylamino-sulfonylmethyl)-5-[Z-(p-methylstyrylsulfonylmethyl)]-1,3,4-oxadiazole displayed slightly higher antioxidant activity than the

A survey of liquid crystalline oxadiazoles

, 2008
We propose a survey of those oxadiazole compounds, which are mesogenic. We will see that they can have bend-shaped molecules, a biaxial nematic phase, or other interesting peculiarities in the nematic and smectic phase.
