As a preliminary to a synthesis of the diastereomeric 5-(3′-pyridyl)-prolines, which will be reported in a subsequent paper, a preparation of the analogous 5-phenyl-prolines is described. As a result of the reaction sequence, a mixture of the two d

Sunflower (Helianthus annuus L.) plants were grown on nutrient solution with ammonium nitrogen. After 12 days of growth the ammonium in the nutrient solution was labeled with 15N (99%). Three hours later glutamine-N in the xylem exudate was labeled f
