The labelling patterns in retrorsine (1) derived biosynthetically from [1,4-2H4]- and [2,3,-2H4]-putrescine have been established by 2H n.m.r. spectroscopy; in the former case the formation of (9S)-[9-2H]retrorsine (12) is consistent with stereospecific addition of hydrogen to the re-face of an aldehyde precursor (RC2HO).
In the presence of ultrasound various mono-, di-, and α,β-unsaturated cyanides were reduced with Cu-Al alloy in NaOD-D 2 O and THF to the corresponding deuteriated aliphatic amines, such as nonylamines, Putrescine, and 1,6-hexanediamine, in high deuterium content.

stereospecific synthesis of chirallydeuteriated (S-adenosyl-S-methylsulfonio)propylamines and several chirallydeuteriated spermidine (-)-camphanamide derivatives has allowed the elucidation of aminopropyltransferase stereochemistry by using /sup 1/H NMR techniques. Putrescine aminopropyltransferase (spermidine synthase) isolated from Eschierchia coli catalyzed the synthesis of chirallydeuteriated spermidines
