16 - 198Enantioselective Synthesis of β-Amino Acids. Part 9. Preparation ofEnantiopure α,α-Disubstituted β-Amino Acids from 1-Benzoyl-2(S)-tert-butyl-3-methylperhydropyrimidin-4-one. — The alkylated aminoacid derivatives (I) are alkylated a second time via their corresponding enolateswith high diastereoselectivity to give after hydrolysis enantiopure α,α-dialkylβ-amino acids. — (JUARISTI, EUSEBIO; BALDERAS, MARGARITA;RAMIREZ-QUIROS, YARA; Tetrahedron: Asymmetry 9 (1998) 21, 3881-3888;Dep.
