Diethyl 4-hydroxy-4-methyl-6-oxo-2-phenylcyclohexane-1,3-dicarboxylate

Abstract

In the title mol-ecule, C<inf>19</inf>H<inf>24</inf>O<inf>6</inf>, the cyclohexa-none ring adopts a chair conformation. The dihedral angle between the phenyl ring and the best plane through the six atoms of the cyclohexa-none ring is 89.68 (7)°. In the crystal structure, mol-ecules are linked via pairs of inter-molecular O - H?O hydrogen bonds into centrosymmetric dimers and these dimers are connected by C - H?O inter-actions into columns down the a axis.
