Procedure 'one pot' of obtaining the Hajos dione.

摘要

Procedure "one pot" of obtaining dione Hajos.; The present invention relates to the synthesis "one pot" or in one step, the dione of wedges using an ionic reaction medium. the first stage Michael reaction is described using an ionic liquid swguida reaction catalyzed aldol condensation of L-Proline. Said ionic medium, preferably [Mmin] [MeSO_ {4}], acts as a solvent and as a catalyst in combination with the catalyst. The process of the invention achieves a yield in obtaining the Hajos dione of 84%.
