New enantioselective synthesis of 4-hydroxy-2-oxopyrrolidine-N-acetamide (oxiracetam) from malic acid
摘要:
The enantioselective synthesis of oxiracetam has been accomplished from readily available optically active D(+) and L(-) malic acids. The key step of the described method involves the selective reduction of a chiral cyclic diimide; in this way, both enantiomers of 4-hydroxy-2-oxopyrrolidine-N-acetamides were prepared.
