Josien,Martin Chassaing
, p. 6547 - 6550 (1991)
L-diphenylalanine and L-9-fluorenylglycine were prepared from a sultam-derived 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.
