Web7. Some of the most important building blocks for synthesis are very simple mol- ecules. Although cyclopentanone and cyclohexanone are readily available com- mercially, an understanding of how they can be made from simpler molecules is instructive. The following are possible retrosynthetic analyses for both of these ketones. http://www.orgsyn.org/demo.aspx?prep=CV1P0192#:~:text=Cyclopentanone%20can%20be%20prepared%20from%20adipic%20acid%20by,reported%20using%20barium%20carbonate%20as%20a%20catalyst.%209
