✦ Synopsis


Isomerically pure 3-benzyloxy-3-hydroxyethylazetidin-2-ones, prepared by non-chelation controlled L-Selectride reduction of 3-acetyl-3benzyloxyazetidin-2-ones, have been converted into the both possible 3-spiroepoxyazetidin-2-ones.

In this Letter, we report a novel approach to the preparation of 3-anilino-pyrazin-2(1H)-ones and 3-anilino-quinoxalin-2(1H)-ones from the corresponding 3-halo pyrazin-2-amines and 3-haloquinoxalin-2-amines, using a microwave-mediated Smiles rearrangement.
