C-Terminal tryptophan containing peptides have been converted into 1-peptidyl-3,4-dihydro-β-carboline-3-carboxylic acids by acid catalyzed isomerization of their azlactone derivatives. The main properties of these abnormal peptides are a strong absorption around 360 nm an intense yellow fluorescence and ability to generate reactive carbanions when dissolved in basic media. This tryptophan conversion
含C-末端色氨酸的肽通过其氮杂内酯衍生物的酸催化异构化已转化为1-肽基-3,4-二氢-β-咔啉-3-羧酸。这些异常肽的主要特性是在360 nm附近有很强的吸收能力,发出强烈的黄色荧光,并且溶解在碱性介质中时能够产生反应性碳负离子。该色氨酸转化以高收率进行并且具有普遍的适用性。
