Facile synthesis of(R)-1-(1H-indol-3-yl)propan-2-amines hydrochloride from Ketones

  Two kinds of (R)-1-(1 H-indol-3-yl)propan-2-amines were prepared through a five-step sequence procedure.The intermediate ketones were prepared by a modified Nef reaction using nitroalkenes to react with Fe-HCl.Condensation of (R)-(+)-2-methyl-2-propanesulfinamids with ketones, which was followed by a final desulfonation treatment with a solution of hydrochloride/methanol under mild conditions, optical pure (R)-sulfonamides could be synthesized.Without further chiral separation processing, the target products of (R)-l-(1H-indo1-3-yl)propan-2-amines could be obtained with higher yield and excellent enantiopurity (over 99% e.e.), thus it was time-saving and cost-saving.
