title: Isolation of D-4-chlorotryptophane derivatives as auxin-related metabolites from immature seeds of Pisum sativum.
abstract: Three active compounds which induce hypocotyl swelling in Phaseolus mungo were isolated from immature seeds of Pisum sativum. For purification of the compounds, our three-step procedure (counter-current distribution, Sephadex LH 20, and partition chromatography on silicic acid) were used. The chemical structures of two of the compounds were determined by synthesis to be α-N-carboethoxyacetyl- and α-N-carbomethoxyacetyl-D-4-chlorotryptophane. D-4-Chlorotryptophane is the first naturally occurring chlorinated amino acid found.
