Abstract
Racemic norepinephrine was synthesized with three deuterium atoms on the alkyl chain. The deuteration was accomplished by D/H exchange on the intermediate, dibenzylaminodihydroxyacetophenone, followed by reduction of the keto moiety and cleavage of the benzylβprotecting groups with deuterium gas. Noradrenalone was also shown to be a possible intermediate for the incorporation of ^18^0 into norepinephrine.

Stable isotope labeled 3-acetyldeoxynivalenol (3-AcDON) was synthesized in excellent yield from deoxynivalenol as starting material. This is the first synthesis of a stable isotope labeled type-B trichothecene suitable as internal standard for HPLC-MS/MS or GC-MS analysis of trichothecene mycotoxins
The synthesis of a lk-labeled and two stable isotope-labeled analogs of CGS 16617 is described. The synthe tic method involved the preparation of tetrahydro-3--bromo-1-benzazepin-2-one, labeled with a 14C or four deuterium atoms, followed by introduction of two side chains at 1-and 3-positions. Th
