The absolute configuration of (+)-4-(6-methoxy-2-naphthyl)butan-2-ol ((+)-MNBO), a nabumetone metabolite, was determined using 1-fluoroindan-1-carboxylic acid (FICA). Both enantiomers of the FICA methyl esters were derivatized to diastereomeric esters of (+)-MNBO by an ester exchange reaction. The results of 1H- and 19F-NMR spectroscopy of the diastereomeric FICA esters of (+)-MNBO confirmed the absolute
萘丁美酮代谢产物(+)-4-(6-甲氧基-2-萘基)丁-2-醇((+)-MNBO)的绝对构型是使用1-氟茚满-1-羧酸(FICA)确定的。通过酯交换反应,将FICA甲酯的两种对映异构体衍生为(+)-MNBO的非对映体酯。(+)-MNBO的非对映异构FICA酯的1H-和19F-NMR光谱结果证实(+)-MNBO的绝对构型为(S)。
