摘要：

(Chemical Equation Presented) Direct support: The title compounds have been used as polymeric organocatalysts (see structure) in the asymmetric alkylation of a glycine derivative to give the corresponding phenylalanine with high enantioselectivity. The polymeric catalyst can be reused without loss of its catalytic activity. © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
