                                    A number of natural products with interesting biological properties are based on a diketopiperazine scaffold. In this context, we have developed a diversity oriented and efficient synthetic strategy to highly functionalized proline-based diketopiperazines. In this paper we describe the stereoselective synthesis of various scaffolds resembling abundant natural product core structures. These scaffolds can be conjugated to a solid phase and are thus platforms for the construction of small compound libraries and the synthesis of natural products with diketopiperazine cores.
