Improved synthesis of (RS)-3-oxocyclopentanecarboxylic acid: Characterisation of the intermediates

An improved synthesis of the (RS)-3-oxocyclopentanecarboxylic acid (7) in 22% overall yield is described together with the characterisation of the intermediates. The reaction sequence proceeds via Dieckmann cyclisation of ethyl butane-1,2,2,4-tetracarboxylate (1), subsequent acidic hydrolysis and a final decarboxylation. Furthermore, the yet unknown composition of the mixture obtained intermediately from the Dieckmann cyclisation has been elucidated by means of 1H and 13C NMR-spectroscopy.
