荸荠中一种生物碱(MTC)的鉴定和绝对构型的确定
THE STRUCTURE AND CONFIGURATION OF ALKALOID (MTC) IN HELEOCHARIS DULCIS
【摘要】 本文介绍了荸荠中存在的一种生物碱(MTC)的提取、分离和鉴定,并用化学合成和~1HNMR NOESY谱数据确定其绝对构型。
【Abstract】 An alkaloid, (-)(1S,3S)-1-methyl-1 ,2,3,4-tetrahydro-β-carboline-3-carboxylic acid lated from Heleocharis dulcis was identified. The absolute configuration was decided by 1H-1H CO 1H-1H NOESY and an asymmetric synthesis of MTC.
