Question

Draw structural formulas for the α,β-unsaturated aldehyde or ketone and the lithium diorganocuprate (Gilman reagent) that could be used in the synthesis of the compound shown below. You do not have to consider stereoisomerism. In cases where there is more than one answer, just give one. If one structure has a copper-lithium bond, draw the lithium ion in a separate sketcher. Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. Separate multiple reactants using the "+" sign from the drop-down menu.
