 cis (Z) jasmone 

(Can. J. Chem. 1978, Vol 56, p2301)

e.g. How might we attempt to make Z jasmone – an important constituent of many perfumes?

In fact one synthesis uses the following as carbon sources:

It is not clear from this however, how the chemistry might be done!  Therefore just being given the starting materials is not sufficient to help plan a synthesis.
Note the importance of CCBFR.

We need a logical planning method.
