Does anyone know how can I synthesis cyclopentane from molecules that doesn't have more than two carbon atoms?
Thanx for your help!

Work backward. This is called retrosynthesis. Cyclopentane comes from cyclopentanone. Cyclopentanone comes from the base-catalyzed cyclization of diethyl or dimethyl adipate to methyl or ethyl cyclopentanone-2-carboxyate. Isn't this the Dieckman condensation? One hydrolyzes the ester, the free carboxylic acid loses CO2, and one gets cyclopentanone.
