- W803471880 abstract "2-Piperidylglycine will be a model compound for the synthesis of antitumor agent 593A. 2-Piperidylglycine may be synthesized by alkylation of glycine equivalent to C-2 position of piperidine ring. -Valerolactam was reacted with trimethyl oxonium tetrafluoroborate to give 2-methoxy-1-piperideine. The imino ether was not condensed with ethyl phthalimidoacetate, one of glycine equivalents, but with ethyl nitroacetate to afford ethyl nitro-2-piperidylene acetate. The subsequent hydrogenation over Pt/C gave ethyl 2-piperidyl glycinate. Because the Z-configuration of the condensed product was assigned by nmr, the stereochemistry of ethyl 2-piperidyl glycinate different from that of Agent 593A." @default.
