Photochemical behaviors of the pyrazinone derivatives 5,6,7,8-tetrahydroquinoxalin-2( 1H)-ones la-c and 1,5,6,7,8,9-hexahydro-2H-cyclohepta[b]pyr~in-2-one Id were investigated. Dye-sensitized photo-oxygenation of la+ gave the 1 :1 adducts 5a-c of the corresponding 3,8a-epidioxy-3,5,6,7,8,8a-hexahydr
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.
