Feeding experiments with (2R)- and (2S)-[2-2H]putrescine on Senecio isatideus plants have shown that hydroxylation at C-7 of retronecine proceeds with retention of configuration and formation of the 1,2-double bond involves removal of the pro-S hydrogen and retention of the pro-R hydrogen at C-2 of retronecine.
