The aldol product is either a β-hydroxyaldehyde or a β-hydroxyketone. This reaction is an important synthetic mechanism that produces large molecules through the formation of …
WebAn aldol reaction involves the condensation of two carbonyl compounds to form a ß-hydroxyaldehyde or ß-hydroxyketone, the aldol product. The typical aldol reaction involves self condensation of the reactant ketone or aldehyde wherein one molecule adds to the other of the same type. An example of a self-condensation aldol reaction is shown in ... Web24 aug. 2001 · The structures of cycloalkanone-based threo and erythro aldols were investigated by systematic introduction of stereo-determining factors. The combination of single-crystal X-ray analysis and cryoscopic measurement and solution NMR and IR studies elucidated the detailed geometry of these typical aldols. Currently, X-ray diffraction is the …
WebThe products of aldol reactions often undergo a subsequent elimination of water, made up of an alpha-hydrogen and the beta-hydroxyl group. The product of this β -elimination reaction is an α,β-unsaturated aldehyde or ketone. Base-catalyzed elimination occurs with heating.

Formation of enolate ion 2. Using the enolate ion as a nucleophile. The 1st step is a reversible step. If you think that the kinetically favoured enolate ion will be formed fast then you are wrong as it also disappears faster.
WebThen we would form an alkoxide. Then we would go ahead and protonate to form our aldol. Once again just to save time, not an exact mechanism but thinking about our intermediate as being this aldol. Because we have heat we're probably going to once again form a conjugated product here and keep going for the complete aldol condensation.
