Preparation of New Derivatives of Enaminolactones

Abstract

The 1,3-dipolar cycloaddition reaction of Substituted benzyl azides and quomarinee  was  studied . Where interacted Substituted benzyl azides with quomarine produced seven vehicles of the type Inaminolactone (a, b, c, d, e, f, g).The 1,3-dipolar cycloaddition reaction of 3- methoxy benzyl azide and quomarinee carried out in p-xylene at reflux. and product was formed in high yield .The isolated and purified products were characterized by spectral methods , IR , ¹HNMR , Cosy , ¹³CNMR , Dept-135 and GC/MS.  Moreover, the compounds belong to Enaminolactones class and compounds of great importance,are used as inhibitor to  corrosion and rust and these compounds have therapeutic value, and they are  intermediate compounds in organic synthesis for the preparation of some medical products. The reactions 1,3- dipolar cycloaddition of substituted benzyl azides with quomarine using to one time for  preparing  the enaminolactones, and this way is new.
