WebIn this video, we're going to think about doing things in reverse. So we're going to start with a retro aldol reaction and see how that way of thinking can apply to retro synthesis. And so let's start with cinnamaldehyde right here. And if we do a retro aldol reaction, the mechanism is pretty much the exact reverse of an aldol condensation. WebAldol condensation is an important synthetic method widely used in organic synthesis. Development of catalytic methods that avoids the production of stoichiometric by …
WebMECHANISM OF THE ALDOL REACTION. Step 1: First, an acid-base reaction. Hydroxide functions as a base and removes the acidic α-hydrogen giving the reactive enolate. Step 2: The nucleophilic enolate attacks the aldehyde at the electrophilic carbonyl C in a nucleophilic addition type process giving an intermediate alkoxide. Step 3:
WebMar 27, 2024 · A series of HZSM-5 with different amount of Brönsted acid sites were prepared by sodium ion-exchange method and their condensation performance were investigated. An increase in Brönsted acid sites served as the active center for the aldol condensation of aldehydes and ketones, leading to a greater overall yield of the desired … WebYou are doing a "crossed aldol" condensation with two different carbonyl compounds.
