, p. 16645 - 16662 (2007/10/03)
All four optically pure isomers of the highly conformationally constrained novel chimeric amino acid, β-isopropylphenylalanine or β- phenylleucine, were asymmetrically synthesized in five to six steps in 20 - 25% overall yield. Computer-assisted molecular modeling revealed that the β- isopropyl group in these chimeric amino acids plays the dominant role in determining the most favorable side chain conformations.

, p. 1563 - 1566 (2007/10/03)
All four optically pure isomers of a highly conformationally constrained unusual amino acid, β-isopropylphenylalanine, have been asymmetrically synthesized.
Syntheses of highly constrained β-aryl isohexanoic acid derivatives via asymmetric Michael addition
Liao, Subo,Han, Yinglin,Qiu, Wei,Bruck, Michael,Hruby, Victor J.
, p. 7917 - 7920 (2007/10/03)
A series of enantiomerically pure highly sterically hindered β-branched isohexanoic acid derivatives have been synthesized with high diastereoselectivity via asymmetric Michael addition. The X-ray crystal structure of (4S,3'S)-3-[3'-(2,6-dimethylphenyl)is
