Show how you would accomplish the following conversions in good yields. You may use any necessary reagents.

A reagent is a substance that is added in the reaction to form the product from the reaction means they are used to complete the chemical reactions.

It is the reaction of the enolate ion with carbonyl group other than reacting carbonyl species which leads to forming$\mathbf{\alpha }\mathbf{,}\mathbf{\beta }$ unsaturated aldehyde or ketone.

It is also called mixed aldol condensation because reacting carbonyl is react with different carbonyls to form the product.

As the hydrogen is protonated from the reacting species formation of enolate ion occurs which combines carbonyl other than reacting carbonyl species followed by the removal of ${\mathrm{OH}}^{-}$formation of $\mathrm{\alpha },\mathrm{\beta }$unsaturated aldehyde occur.

The reaction between derivative of furan with NaOH lead to the formation of $\mathrm{\alpha },\mathrm{\beta }$unsaturated carbonyl compound.

A reaction followed as:

Mixed aldol condensation
