Structures of the synthesized products were identified by using chemical and physical methods such as elemental analysis, IR, <sup>1</sup>H-NMR and MS. The obtained results were compared with those reported, it was found that neither of the synthesized compounds was Cairomycin A.</span></p>}, number={4}, journal={Science Journal of University of Zakho}, author={Hussain, Faiq H.
