%X 3-Methylcyclohexenones may be converted into dihydroindol-7(6H)-ones by conversion of the epoxide into the 2-benzylamino-3-methylcyclohexenone, which reacts with dimethyl- formamide dimethyl  acetal to give N-benzyldihydroindol-7(6H)-ones. The limitations of the process are discussed, as is the failure to convert the dihydroindol-7(6H)-ones into dihydropyrroloazepinediones by Beckmann or Schmidt rearrangements. An example of the latter compounds was made by a simple procedure from pyrrolecarboxylic acid.
