Notes:
Heating of 3-isobutylidene-2,5-diketopiperazines 1 or 4, maleinimide or 2,3-dichloro-5,6-dicyano-p-benzoquinone with tert-butyl iodide in toluene gave rise to hydrogenation of the conjugated C—C-double bond affording 3-isobutyldiketopiperazines 2(rac) and 3(rac), succinimide, or 2,3-dichloro-5,6-dicyanohydroquinone, respectively. Furthermore, an interesting N—O migration of a benzoyl group as well as reductive aromatization to pyrazines 5 and 6, respectively, were observed.
