1-Cyclopentenecarboxylic acid Chemical Properties,Usage,Production

Chemical Properties

White to pale yellow powder

Uses

1-Cyclopentenecarboxylic Acid can be used for enantioselective 1,3-dipolar cycloadditions of diazoacetates and solid-phase synthesis of substituted indolines. It can also be used to develop antagonists for A1- and A2-adenosine receptors.

Uses

1-Cyclopentenecarboxylic acid was used in synthesis of cis-8-hexahydroindanecarboxylic acid via Diels-Alder reaction with butadiene. It was also used in synthesis of isoxazole derivatives.

General Description

1-Cyclopentenecarboxylic acid was evaluated as a new effective anticonvulsant during Anticonvulsant Screening Program (ASP) of Antiepileptic Drug Development Program.
