Application

Valeroyl chloride was used in the enantioselective synthesis of propylisopropyl acetamide (PID), an amide analog of the major antiepileptic drug valproic acid. It was also used in the synthesis of (4R, 5S-4-methyl-3-(1-oxopentyl)-5-phenyl-oxazolidinone.

Propylisopropyl acetamide (PID), an amide analogue of the major antiepileptic drug valproic acid (VPA), possesses favorable anticonvulsant and CNS properties. PID contains one chiral carbon atom and therefore exists in two enantiomeric forms. The purpose of this work was to

The teratogenic activities of R(+)- and S(-)-2-n-propyl-4-pentynoic acid (R and S-4-yn-VPA), the enantiomers of the highly teratogenic valproic acid (VPA) analogues (+/-)-4-yn-VPA, were investigated in mice. The enantiomers were prepared via asymmetric synthesis, each in three steps employing the chiral
