- A key step in the synthesis of donepezil is a directed aldol reaction that forms α,β- unsaturated carbonyl compound X. What carbonyl starting materials are needed to prepare X using a directed aldol reaction? What reagents are needed to convert X to donepezil?arrow_forwardDraw the products formed in each crossed aldol reaction.arrow_forwardDraw the aldol product for the reaction of the aldehyde shown with NaOH. Assume the reaction is run under conditions that allow the reaction to stop before dehydration. u H NaOHarrow_forward
- The following molecule is formed in a mixed aldol condensation reaction. organic starting materials B-hydroxycarbonyl HO NaOHarrow_forwardWhy is the Aldol reaction often called an Aldol condensation? 1) The initially formed b-hydroxy carbonyl compound loses an oxygen atom 2) The initially formed b-hydroxy carbonyl compound loses a hydrogen atom 3) The initially formed b-hydroxy carbonyl compound loses water 4) The initially formed b-hydroxy carbonyl compound loses a hydroxyl grouparrow_forwardWhat carbonyl starting materials are needed to prepare each compound using a directed aldol reaction?arrow_forward
