Abstract
Synthesis of some polycyclic compound from 5-phenylcycolohexane -1,3- dione and its derives: Although many cyclohexanone -1,3- diones being employed in this work , it became desirable to study the behavior of such diones have three active centers at C-2 , C-4 and C-7 in this synthesis . as a part of this work , it became desirable to study the behavior of such diones which have three active centrrs at C-2 ,C-4 and C-6 in this synthesis.
