Summary

In the course of an attempted elimination reaction starting from an isothiochromane derivative substituted with an amino-alcohol moiety, a benzo[c]thiophene derivative formed via a rearrangement reaction was isolated unexpectedly. Its constitution was confirmed unambiguously via17O-NMR-spectroscopy.

Zusammenfassung

Im Verlauf einer versuchten Eliminierungstreaktion wurde ausgehend von einem Aminoalkoholderivat eines Isothiochromansystems unerwarteterweise ein Benzo[c]thiophen-derivat isolert. Die Konstitution des Umlagerungsproduktes wurde eindeutig durch17O-NMR-Spektroskopie bestätigt.
