A Process for preparing carboxylic esters of a mixture of structurally branched C9 monocarboxylic acids proceeding from 2-ethylhexanol is characterized in that
(a) 2-ethylhexanol is dehydrated to an octene mixture in the presence of a catalyst;
(b) the octene mixture obtained in step a) is reacted in the presence of a transition metal compound of group VIII of the periodic table of the elements with carbon monoxide and hydrogen to give a mixture of isomeric isononanals;
(c) the mixture of isomeric isononanals obtained in step b) is oxidized to a mixture of structurally branched C9 monocarboxylic acids; and
(d) the mixture of structurally branched C9 monocarboxylic acids obtained in step c) is reacted with alcohols to give carboxylic esters.

2-ethyl-3-methyl-butyl-carbamate (34) and 2-ethyl-3-methyl-pentyl-carbamate (38) also exhibited potent activity in the pilocarpine-SE model 30 min postseizure onset. Extending the aliphatic side chains of homologous carbamates from 7 to 8 (34 to 35) and from 8 to 9 carbons in the homologues 38 and 43 decreased the activity in the pilocarpine-SE model from ED50 = 81 mg/kg (34) to 94 mg/kg (35) and from 96 mg/kg (38)

Valproicacid (VPA, 1) is a major broad spectrum antiepileptic and central nervous system drug widely used to treat epilepsy, bipolar disorder, and migraine. VPA’s clinical use is limited by two severe and life-threatening side effects, teratogenicity and hepatotoxicity. A number of VPA analogues and their amide, N-methylamide and urea derivatives, were synthesized and evaluated in animal models of

Process for preparing the vinyl ester of isononanoic acid starting out from 2-ethylhexanol, characterized in that (a) 2-ethylhexanol is dehydrated in the presence of a catalyst to form octene; (b) the octene obtained in step a) is converted into an isononanoic acid having one more carbon atom; and (c) the isononanoic acid obtained in step b) is converted into the corresponding vinyl ester.
