Abstract

RODRIGUEZ-GARNICA, Cristina et al. Diastereoselective Alkylation of Chiral Glycinate Derivatives Containing the α-Phenylethyl Group. J. Mex. Chem. Soc [online]. 2011, vol.55, n.3, pp.148-153. ISSN 1870-249X.

Derivados quirales novedosos de glicinato (S)-6 y (S)-7 conteniendo el grupo α-feniletil fueron preparados y estudiados como precursores potenciales de α-aminoácidos α-sustituidos. En particular el auxiliar quiral N-(l-feniletil)benzamida mostró estereoinducción sustancial (78:22 dr) en la alquilación del enolato (S)-7-Li. La adición de DMPU no mostró un efecto apreciable en la diastereoselectividad.

Keywords : Alquilación; diastereoselectiva; enantioselectiva; enolatos de litio; glicinato; amino ácidos.
