Utilizing 1-aryloxyindole derivatives, we found a new type of [3,3] sigmatropic rearrangement reaction. We named it as ipso [3,3] sigmatropic rearrangement. The product structures are strictly determined by X-ray crystallographic analysis. Normal [3,3] sigmatropic rearrangement of 1-hydroxyindole derivative was found to be a useful synthetic method for 2H-pyrazino[1',2':1,5]pyrrolo[2,3-b]indole-1,4-dione derivative.
Simple synthesis of 1,3,4,5a,6,10b,11,11a-octahydro-2H-pyrazino[1′,2′:1,5]pyrrolo[2, 3-b]indole derivatives based on 1-hydroxyindole chemistry

3-Substituted (3S,6S)-6-(1-hydroxyindol-3-ylmethyl)-2,5-piperazinediones are prepared for the first time. They are shown to be suitable intermediates for the synthesis of 3,10b-disubstituted (3S,5aR,10bS,11as)-1,3,4,5a,6,10b,11, 11a-octahydro-2H-pyrazino[
