## Abstract The synthesis of Asaley labelled with ^14^C in the mustard (Asaley‐must‐^14^C) or the leucine (Asaley‐leu‐^14^C) moiety is described. In the former, ethyl pamino‐N^α^‐acetyl‐DL‐phenylalanyl‐L‐leucinate was reacted with ethylene oxide(U)‐^14^C to give the bis(hydroxyethyl)amino analogue,

## Abstract A number of synthetic approaches are assessed to prepare allantoin labelled with ^14^C given certain requirements and technical limitations. A method that fulfils these criteria is described to achieve the synthesis of highly pure ^14^C‐labelled allantoin with the label introduced to th
14C labelled Metribuzine was synthetised in a five step synthesis firom sodium [l-14C]pivalate (trimethyl acetic acid) via o-brom0-[2-~~C]pinacoline (l-bromo-3,3-dimethyl-butan-2-on) and trimethyl [2-14C]pyruvic acid. The total yield was 30% (calculated on sodium pivalate).
## Abstract Hexazinone ‐ a s‐triazine type contact herbicide ‐ was labelled with ^14^C for the investigation of metabolic pathways. A convenient synthesis was elaborated for labelling of the carbon atom in the 6 position of the triazine ring. The molar activity of Hexazinone was 797.0 MBq/mmole (21
## Abstract PHA‐690509, a cyclin‐dependent kinase A inhibitor, has been labelled with carbon‐14. [^14^C]PHA‐690509 was obtained via a three‐step procedure in 10% overall radiochemical yield starting from [^14^C]thiourea **3**. Copyright © 2007 John Wiley & Sons, Ltd.
## Abstract The arylpiperazine PNU‐243922 (**1**) has been labelled with ^14^C. A two‐step sequence starting from the ^14^C labelled alcohol **6a** led to radiochemically pure (>98%) [^14^C]PNU‐243922 with a specific activity of 546 MBq/mmol Copyright © 2002 John Wiley & Sons, Ltd.
