Asymmetric synthesis of L-diphenylalanine and L-9-fluorenylglycine via room temperature alkylations of a sultam-derived glycine imine
摘要:
L-diphenylalanine and L-9-fluorenylglycine were prepared from a sultam-derivated glycine imine 3 via room temperature-asymmetric-alkylation/ hydrolysis/mild-sultam-clivage. The L-configuration was ascertained using an X-ray analysis of the alkylation product 4b.
