β¦ Synopsis
The syntheses of tetradeuterated pristanic and phytanic acids, suitable for isotope dilution quantitation of pristanic and phytanic acids in plasma, is described. The key reaction, a Favorsky rearrangement, which simultaneously generates a methyl branch and incorporates deuterium, should be suitable for the preparation of other isotopically-labelled branched chain acids.

## Abstract Easy preparative scale syntheses of deuterium labelled atropine and scopolamine are described. [^2^H~3~]βatropine and [^2^H~3~]βscopolamine are obtained in good yield and good isotopic purity in two steps starting from the unlabelled alkaloids. Copyright Β© 2009 John Wiley & Sons, Ltd.
Convenient syntheses of 2,4-,a,a-and 5,B-deuterium labelled 6-hydroxydopamines have been developed. 2,4,5-Trimethoxybenzaldehyde (1) was reductively aminated to give 2,4,5-trimethoxybenzylamine (2). Quaternization of the amine with methyliodide followed by displacement with cyanide gave 2,4,5-trimet
