General description

3-Oxo-1-cyclopentanecarboxylic acid , also known as 3-oxocyclopentanecarboxylic acid, is a keto acid derivative. It undergoes Curtius rearrangement with diphenyl phosphoryl azide and triethylamine in tert-butanol to form the corresponding boc-protected 1-(3-oxo)urea derivative.

Application

3-Oxo-1-cyclopentanecarboxylic acid may be used in the preparation of 3-hydroxycyclopentanecarboxylic acid via hydrogenation.
Substrate used in a study of biohydroxylation with mutants of cytochrome P450 BM-3.
