Synthesis of LY503430 by using a selective rearrangement of β-amino alcohols induced by DAST

Abstract

LY503430, an optically active β-fluoroamine, is a potential therapeutic agent for the Parkinson's disease. Different strategies have been studied to synthesize this molecule using a regioselective and stereospecific rearrangement of β-amino alcohols into β-fluoroamines induced by DAST. This reaction allowed the synthesis of LY503430 with an excellent enantiomeric excess.
