Page/Page column 14, (2011/10/02)
Disclosed are β-amino acids that are unsubstituted in the β position; that are substituted in the β position with an aryl group; that are substituted in the α position with an aryl group; that bear two substituents in the α position; and/or that are substituted in the α and β positions with groups which, together with the carbon atoms at the α and β positions, form a ring. Also disclosed are methods for making the above-mentioned β-amino acids and other β-amino acids which involve providing an α,β-unsaturated imide; converting the α,β-unsaturated imide to a 2-substituted-isoxazolidin-5-one; and converting the 2-substituted-isoxazolidin-5-one to a β-amino acid.

This manuscript describes a highly diastereo- and enantioselective intermolecular radical addition/hydrogen atom transfer to α,β-disubstituted enoates. Additionally, we show that anti-propionate aldol-like products can be easily prepared from α-methyl-β-acyloxyenoates in good yields and high diastereo- and enantioselectivities. Copyright
