Abstract
Abstract The cyclization of ethyl 6-oxo-5-phenylheptoate, by sodium ethoxide in ethanol, has now been shown to give 6-oxo-5-phenylheptoic acid, 2-acetyl-5-phenylcyclopentanone, 3-ethoxycarbonyl-2-methyl-1-phenylcyclopent-1-ene and 3-ethoxycarbonyl-2-methyl-1-phenylcyclopent-2-ene. The material previously described as a hydrate of 4-phenylcycloheptane-1,3-dione is in fact a mixture of 6-oxo-5-phenylheptoic acid and 2-acetyl-5-phenylcyclopentanone.
