A Convenient Extension of the Wessely-Moser Rearrangement for the Synthesis of Substituted Alkylaminoflavones as Neuroprotective Agents in vitro.

A series of 8-alkylamino-5,7-dihydroxyflavones was prepared from chrysine via a seven step sequence. The synthesis of their 6-alkylamino isomers could be subsequently accomplished through a convenient extension of the Wessely-Moser rearrangement. These compounds were found to be efficient neuroprotective agents in vitro.
