(S)-(-)-1-Amino-1-phenylpropane Structural

What is (S)-(-)-1-Amino-1-phenylpropane?

The Uses of (S)-(-)-1-Amino-1-phenylpropane

(S)-(-)-1-Amino-1-phenylpropane is used in the synthesis of a new series of L-Aspartyl-D-amino amide sweeteners. They contain a sweetness potency 2000 times that of a 10% sucrose solution. Also, a molecul ar determinant of substrate specificity for transaminases, owing to its chiral carbon.

The Uses of (S)-(-)-1-Amino-1-phenylpropane

For synthesis of optically active products

The Uses of (S)-(-)-1-Amino-1-phenylpropane

(S)-(?)-α-Ethylbenzylamine can be used:

To prepare optically active copolyacrylate polymers with sensing and chiroptical properties.
As a chiral auxiliary in the preparation of enantioenriched indanone derived α-SCF₂H β-keto esters.
