Cyclic Addition of Acetylene Dicarboxylic Acid to Some New Aldonitrones Containing 1,3,4 Thiadizol Ring

Abstract

Nine new aldonitrons containing 1,3,4 – thiadizole ring were prepared and characterized by using different spectroscopic methods . Then a cyclic addition reaction with acetylene dicarboxylic acid for nine nitrones was carried out .Only one reaction was succeeded to give the 1,3 –dipolar cyclic addition producing 3- (4 – chloro phenyl (5 – thio – 1,3,4 – thiodizoyl)- 4,5 – dicarboxyl – isoxazoline .
