A Convenient Synthesis and Spectral Studies of Diamines Derivatives

Abstract

<div>A new series of substituted anthranilic esters derivatives linked with a 1,3-dithiolane and</div><div>benzyloximino moiety was synthesized using the simple esterfication reaction and products were</div><div>fully characterized. The isolated yields of these compounds range from 59 to 96%. 1,3-</div><div>dithiolane ester and the benzyloxy substituted diamine derivatives are white solids and stable to</div><div>air and moisture. The synthesized compounds can be exhibits UV-vis absorption properties by</div><div>their structures with a amine or amide group, It is observed that absorption maximum is excellent</div><div>for 2,6-disubstituted benzyloxy esters which can be explained by electron transfer or conjugation</div><div>is steric effect in ortho substitution from the amino group and the amide group.</div>
