Fractional crystallisation of (±)-iso-amarine with mandelic acid: convenient access to (R,R)- and (S,S)-1,2-diamino-1,2-Diphenylethane (cas 103-29-7)s

Add time:08/12/2019    Source:sciencedirect.com

(±)-iso-Amarine can be conveniently resolved via 1:1 salt formation with either hand of mandelic acid. Enantiopure iso-amarine can be acetylated and hydrolysed to give enantiopure 1,2-diamino-1,2-diphenylethanes.
