Alexander Borodin is also credited with the discovery of the Aldol reaction together with Wurtz.
In industry the Aldox process developed by Royal Dutch Shell and Exxon, converts propylene and syngas directly to 2-Ethylhexanol via hydroformylation to butyraldehyde, aldol condensation to 2-ethylhexenal and finally hydrogenation.
3,4-AHBAm is made via the aminoshikimate pathway from L-Aspartate-4-semialdehyde and Dihydroxyacetone phosphate via an enzyme catalyzed aldol condensation followed by ring formation.
