Carnation perfume intermediate, synthesis

The disconnections we have made so far have all been of C-O, C-N, or C-S bonds, but, of course, the most important reactions in organic synthesis are those that form C-C bonds. We can analyse C-C disconnections in much the same way as we ve analysed C-X disconnections. Consider, for example, how you might make this simple compound, which is an intermediate in the synthesis of a carnation perfume.
