✦ Synopsis

RESOLUTION 01; AMINO ACID DIASTEREOXERS BY ME_.-XS OF PACKED COLUMN GAS CHROMATOGRWHY'." The &e&t of an alcohol's structure upon the resolution of its N-allkylated amino acid diastereomeric ester was studied using several packed gas chromatographic columns. Using & 3.3~dimetlqk+butyl-N-trifluoroacetyl derh-atives, fourteen protein amino acid diastereomers could be r=olx-ed to 93 "b or better. &pax-tic acid and proline derivatives could be resolved to 70 @?b and S2 OO, respectively. Arginine, histidine and cystine derivatives were not studied.
