Sažetak

N-Phthaloyl amino acids have proved to be very useful for the syntheses of peptides, diazoketones, homologous optically active B-amino acids, optically active a-amino aldehydes, aminoalkylglyoocals and vinylogs of naturally occurring amino acids. As no description has hitherto been given of the N-phthaloyl derivatives of O-alkyl-DL-serine which would enable the above mentioned syntheses to be carried out with serine, we prepared O-methyl-N-phthaloyl-DL-serine by reacting O-methyl-DL-serine and O-ethyl-DL-serine respectively with phthalic anhydride. Further more, O-ethyl-N-p-tosyl-DL-serine and N-carbobenzoxy-O-ethyl -DL-serine were also prepared.
