Stereochemical studies on aeromatic amino-acids. Part 4. Absolute configuration of 3-Amino-2-phenylpropionic acid
(+)-3-Amino-2-phenylpropionic acid (1) was assigned the (S)-configuration by chemical correlation with (+)-(S)-1-amino-2-phenylbutane (2). O.r.d. and molecular rotation data for this amino-acid and various derivatives are reported and discussed in the light of well known rules which have been applied to α-amino-acids previously.
