A Convenient Synthesis and Spectral Studies of Diamines Derivatives

This is the authors' abstract. We don't add key points for this paper.

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