Visible light photoredox catalysis: regioselective radical addition of aminoalkyl radicals to 2,3-allenoates†
Abstract
The regioselective addition of α-aminoalkyl radicals to 2,3-allenoates by visible-light-mediated electron transfer using 1 mol% of Ru(bpy)3(BF4)2 as a photocatalyst was successfully established. This photoredox protocol is a simple and effective method for the synthesis of unsaturated γ-aminobutyric ester derivatives.
