Products of this chemical reaction often undergo an additional elimination resulting in conjugated systems.  Generally using either sodium or potassium hydroxide as a catalyst, it results in an intermediate alkoxide  from a nucleophilic enolate's addition to a carbonyl group in either ketones or aldehydes before reaching the final beta-product, which is often altered by dehydration. For ten points, name this condensation reaction  whose name combines that of its two final products and which may have been discovered by A
