[1-13C]-bromoacetic acid. The key step in this process was the enantioselective reduction of an intermediate ketone. This synthesis provides, selectively, both enantiomers of the labelled or unlabelled parent compound, (R) or (S)-4,5-dihydroxypentane-2,3-dione (DPD) and was used for an improved synthesis of [1-13C]-AI-2.
描述了群体感应信号 Autoinducer-2 (AI-2) 的新合成路线,并用于从 [1-13C]-溴乙酸开始制备 [4-13C]-AI-2。该过程的关键步骤是中间体酮的对映选择性还原。该合成选择性地提供标记或未标记母体化合物 (R) 或 (S)-4,5-二羟基戊烷-2,3-二酮 (DPD) 的两种对映异构体,并用于改进 [1-13C ]-AI-2。
