| titleOfInvention | Process for the preparation of 3-, 6-substituted 2,5-morpholinediones |
| abstract | A process for making 2,5-morpholinediones of structure (I), wherein each R is independently hydrogen, C1-C12 hydrocarbyl, or substituted hydrocarbyl and at least one R is C1-C12 hydrocarbyl or C1-C12 substituted hydrocarbyl, by reacting an ester of free acid of an N-(α-hydroxyacyl)-α- amino acid substrate of structure (II) wherein each R and R3 is independently hydrogen, C¿1?-C12 hydrocarbyl or C1-C12 substituted hydrocarbyl and wherein at least one R is C1-C12 hydrocarbyl or C1-C12 substituted hydrocarbyl, over a fixed bed catalyst, the reaction being carried out at about 150 °C to about 350 °C, followed by collection of the effluent product. Such morpholinediones are useful as precursors for the preparation of depsipeptide polymers and copolymers. |
