The diastereoisomers of L-1-indanylglycine and L-1-benz[f]indanylglycine, novel topographic tools and anologues of phenylalanine and 2-naphtylalanine, were synthesized from a sultam-derived glycine imine synthon alkylated by judicious electrophiles, and subsequent hydrolysis and sultam-cleavage. An X-ray analysis on one alkylation product established the beta-configuration.
