Cyclic addition of acetylene dicarboxylic acid to some new aldonitrones containing 1, 3, 4 thiadizol ring

الملخص EN

-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
