## Abstract An efficient approach to the enantioselective synthesis of a series of amino acids from either bromoacetyl bromide or glycine is described using a [2,3]‐sigmatropic rearrangement to establish the stereogenic centre at C‐2 under mild conditions. Protected allylglycine **5** is a valuable

## Abstract We report the synthesis of ^11^C‐labelled choline using the reaction of “nocarrier‐added” ^11^C‐labelled methyliodide and 2‐amino‐(N,N‐dimethyl)‐ethanol. After determining the optimum temperature and duration for the reaction, we achieved a radiochemical yield of about 30% and the radio

## Abstract ^11^C‐Labelled benzene derivatives were prepared catalytically by trimerizing acetylene‐^11^C with acetylene and propyne carriers over 1.5 grams of silica‐alumina support activated by potassium chromate (0.2% by weight). Optimized yields of the ^11^C‐labelled aromatics were obtained whe

## Abstract This article describes the radiosynthesis of ^11^C‐labelled S‐adenosylmethionine by an enzymatic process. This methyl donor was prepared by condensation of L‐(methyl‐^11^C) methionine with ATP. The synthesis and purification could be carried out in 20 minutes with a final yield of 80 %.
