Moreover some of the prepared new compounds were subjected to pharmacological testing and the results obtained are summarized .The present investigation involves the synthesis of some unavailable starting materials and intermediates e.g. 2,4-Pentadienoic acid and 2,4-Pentadienol .In addition, the study involved the synthesis of some new compounds .Moreover, certain new compound were subjected to pharmacological screening and the results obtained are summarized .
