Alcohols via aldehydes

Fig. 14. 52. Mechanism of the Li AI If, reduction of carboxylic esters to alcohols via aldehydes.

Waxes are synthesised by reduction of fatty acids to primary alcohols via aldehydes. Primary alcohols react with acyl-CoAs to form esters, aldehydes eliminate carbon monoxide (by decarbonylation) giving rise to hydrocarbons (alkanes). Oxidation of alkanes yields secondary alcohols, and oxidation of secondary alcohols gives rise to ketones.
