SYNTHESIS AND MOLECULAR CRYSTAL STRUCTURE OF DIETHYL-6-HYDROXY-4-(2-HYDROXYETHYLAMINO)-6-METHYL-2-PHENILCYCLOHEX-3-EN-1,3-DICARBOXYLATE
By interaction of diethyl-4-hydroxy-4-methyl-6-oxo-2-phenylcyclohexane-1,3-dicarboxylate with ethanolamine in alcohol environment there has been obtained diethyl-6-hydroxy-4-(2-hydroxyethilamino)-6-methyl-2-phenylcyclohex-3-ene-1,3-dicarboxylate, and by X-ray structural analysis the molecular crystal structure of the latter established. X-ray structural analysis data have determined the conformation of the cyclohexene ring as a distorted half-chair. Orientation of al the substituents, except the OH group is pseudo-equatorial. As well, there have been revealed the intra- and intermolecular hydrogen bonds
Keywords : enamine, cyclohexen ring, conformation, half-chair, intra- and intermolecular hydrogen bonds
